Yes, they do.
The ban stack resets every year.
For example, letâs say you were banned today for one day for âharassmentâ.
If you violated the rules again, your account will be suspended for at least 3 days (Roblox will warn you and tell you this already, so no need to guess or figure it out).
And if you violated the rules again and were banned for 3 days, the next violation will suspend you for at least 7 days (Roblox will also warn you about that)
And if you violated the rules again and were banned for a week, the next violation will terminate your account. (Youâll be warned about that)
I, by myself, havenât tested how true this system are, but I saw it countless times on Reddit and is confirmed by many people.
Keep in mind that there are some violations that terminates your account without a ban or a warning. Some of these violations I noticed are Child Endangerment, Self-Harm/Sucide, Creating, promoting or participating in inappropriate content or behaviour, moving/receiving stolen items, Misusing Roblox Systems, ban evasion, creating accounts just for the purpose of breaking the rules, trading, buying or selling Robux or virtual Robux outside of the Roblox website, and probably some more I forgot to list.
If your account was created one femtosecond before you do these violations, your account will still get terminated.
There are also violations which always temporarily ban your account. The only violation Iâve noticed is creating, promoting or participating in inappropriate content or behaviour related to terrorism. (This always bans you for a week)
Unauthorized/Disputed charges also was used to terminate your account, but Roblox changed it to a temporary ban, meaning if Roblox detected unauthorized/disputed charges on your account, youâll either be banned for 6 months or a year.
And one violation that usually gives you a warning is uploading inappropriate assets. Unless you used/promoted them inside the platform, youâll only be warned. (This is what I noticed. They may ban you if the asset were extremely inappropriate or sexual)
Also note that when a ban is successfully appealed and the ban was removed, it wonât count in the ban stack and will be removed from your moderation history.
Meaning if you appealed your three-day ban and it was approved, it wonât count in the ban stack and the next violation will still give you a three-day ban, not a seven-day ban.
After a year, the ban stack reset and youâll start from one-day ban again (Or a warning, depending on the violation).
Hope this helps!
