Preface
This guide explains the main difference between clean and dirty dupe methods, how clean and dirty dupes are produced, and how to think about it simply. Dupe glitch publishers can link to this chapter in their posts.
Introduction
Clean and dirty methods both produce duplicate vehicles. The important difference is the license plate on the master vehicle and the plates on the dupes after the glitch.
Master Vehicle (MV) — The vehicle that the created dupes clone from.
Exception: People Duping to Not Sell
If you’re not selling, you can use either method without worry. Clean vs dirty only matters when you sell.
For Everybody
You won’t get in trouble just for creating or owning clean or dirty dupes. You will be punished if you sell a dirty dupe. Punishments are not bans or resets—they affect your ability to profit from dupes (e.g. daily sell limit). Always follow recommended daily sell limits.
Dirty Method
A dirty method is a glitch where the dupes copy the master vehicle’s plate. Without a custom plate on the master vehicle, the method produces dirty dupes by default.
If the MV has plate 12345678, the dupes will have 12345678 too. Every car has a distinct, randomly generated plate by default. When the game sees the same plate on multiple vehicles, it flags them and “detects” them when they’re sold.
That’s why with dirty methods you need a custom plate that you own on the master vehicle before duping. Custom plates use a unique ID that can be shared across vehicles, so dupes that copy that plate don’t trigger the system—you get clean dupes that are safe to sell.
Clean Method
A clean method is a glitch where the dupes get newly generated plates. You don’t need a custom plate on the master vehicle; the method always produces clean dupes.
If the MV has plate 12345678, the dupes’ plates will be something other than 12345678. When these glitches are available, take advantage—aside from the glitch’s own requirements, there’s no extra setup. Dirty methods require having custom plates ready.
FAQ: Clean vs Dirty
Dirty dupes given a custom plate afterwards. Are they safe to sell? Are they clean?
Technically they can be masked as “clean” and might sell, but don’t do it. They’re still fundamentally dirty; the game may see through it and you’ll pay the penalty if it does. Better to be safe than risk it.
Plate cycling. Is it recommended? Is it necessary?
On console, not really. On PC, probably—at least have 2 custom plates. PC dupes are always dirty until the plate is changed. On console, just know whether you’re making clean or dirty dupes; if dirty, don’t sell.
What type of method is GCTF (Give Cars to Friends)?
GCTF is a dirty method. No custom plate on the donor car = dirty dupes; same rules apply.
If my master vehicle is clean, will I produce clean dupes?
The method rules are what matter. Whether the dupes are clean or dirty depends on whether you have your custom plate equipped (dirty methods), not on whether the MV itself is “clean.”
Master vehicle has a Yankton plate. Clean or dirty?
The plate style (background) doesn’t matter—only the plate text (that you own it).
Blanktons
They look blank but still have a plate ID. To be 100% safe, avoid duping them; use a car that has a custom plate you own.
“Cars with no plates”
Every car has a plate as an ID, even if you can’t see or change it. For vehicles like the Arena War Slamvan, put a custom plate on the base model before upgrading; otherwise you can’t fix it later without a merge.
More FAQ: Selling & Limits
I did a dupe over the weekend and sold a couple cars. Now I don’t have access to my custom plates. Help!
If you’ve hit a limit of 1 or 2 for the first time, check for dupe detected vehicles (dupes with generic plates that match). Check garages for custom plates you’ve accidentally deleted from iFruit. If either is true, get rid of those vehicles to clear dupe detection. See the Dupe Detects section below.
I have two characters. Can I sell double the amount?
No. Both characters share the same Social Club account, bank, and daily limit. You don’t get separate limits per character.
What is the daily limit for personal vehicles?
A tunable that limits how many personal vehicles you can sell in a time period to deter duplication exploitation.
Should I worry about getting banned?
No. This isn’t a bypass; think of it as a strategy guide. Nobody is banned or reset for duping—punishments only affect your ability to profit (e.g. daily limit).
If I keep proper spacing between sales, can I hit my limit every day and still increase it?
No. Avoid hitting your limit. It’s recommended to take 60 hours off from selling to let your level adjust.
Can I just not play for a few weeks and my level will adjust?
You don’t need to log in every day and sell to adjust. Going online every few days is enough to keep your limit in good standing.
Do I have to sell exactly 1 less than my limit to move up?
You can sell any amount less than your current limit, or none. Just don’t hit the limit.
If I have DSL on my main character, will I have it on a new character?
Yes. DSL exploit levels are per account. Bypass works because you only hit “soft” exploit levels, not the actual account exploit level.
How the Daily Sell Limit Works
The daily limit for personal vehicles is stored as multiplayer data on Social Club. These stats are read when you enter a mod shop. Depending on stats (vehicles sold, total sold in a period, exploit level, etc.), the game may block you from selling more. Selling too fast or too many raises your exploit level and lowers your daily limit. All times are real-life, not in-game.
How Vehicles Are Classified
- Purchased vehicle: Bought in-game or a dupe of one. Can be sold with no wait at LSC.
- Stolen vehicle: Taken from the street or a dupe of one. 48-minute (or one in-game day) wait to sell; does not count against daily limit.
- Personal vehicle: Has a tracker and/or is in a garage. Sale counts against daily limit. Upgrading a stolen Benny’s-compatible car makes it a purchased vehicle.
Dupe Detects and License Plates
- Dupe detect tracks the last 30 vehicles you’ve used and tracks sales by exact generic plate. Duplicate generic plates get marked dupe detected.
- It stores vehicle model + plate text for the last 7 sales (custom or generic). Both model and plate must match a stored value to trigger.
- As you sell, the oldest stored value drops off.
- You lose the ability to change to custom plates on vehicles with detected plates. After the second dupe-detected vehicle you hit the daily limit message and get restricted to 1 car per 30 hours.
- To get out of dupe detect: Get rid of dupe-detected vehicles (dupe over them or replace with other cars). Don’t sell them—that only worsens your exploit level.
New Daily Sell Limit Guidelines
- First vehicle — 100% of sell price
- Second vehicle — 50% of sell price
- Third vehicle — 20% of sell price
- Fourth vehicle — 5% of sell price
Sell prices reset 18 hours after the last car sold. The old sell limit is still in effect: max 2 cars back-to-back (B2B) without bypass; 3rd triggers DSL. Updated hard-cap for bypass is 9 cars. If you don’t know your exploit level, sell a max of 2 cars in 24 hours. If you know you’re exploit level 0, it’s considered safe to sell up to 9 cars (e.g. 2 every 2 hours). A safe pattern is 2 cars every 2 hours.
If you hit DSL, wait 14 days for exploit level to drop by 1 (e.g. level 3 → 2 after 14 days).
Exploit level limits: old vs new
Daily sell limits per exploit level were reduced. Below are the old and new maximum vehicles per 24 hours (personal vehicles).
| Level | Old limit | New limit |
|---|---|---|
| 0 | 20 | 10 |
| 1 | 6 | 3 |
| 2 | 4 | 3 |
| 3 | 3 | 2 |
| 4 | 3 | 2 |
| 5 | 2 | 2 |
| 6 | 2 | 2 |
| 7 | 2 | 2 |
In practice: level 0 can sell up to 9 in 24h before hitting DSL (10 triggers it). Levels 1–2: max 2 in 24h (3 hits DSL). Levels 3–7: max 1 per 24h (2 hits DSL). The initial threshold was lowered from 5 crosses to 2. Recovery time increased from one week to two weeks.
