A GP has very little control over what shows up in your history. It's mostly all automatic. Any sort of chat or status reset log is done through an automatic system. A GP literally just clicks "reset chat", and they're done. It's automatically stored in history. There's absolutely no way to fake these sort of resets, unless of course you had access to weapons or wherever it's stored, which is something not even the GPA would have.

Any ban have to have one of these automatic resets in there, or if it's an offense such as speedhacking it would need substantial proof. If you appeal a ban and it doesn't have a reset log or a literal video of you speedhacking then it's automatically appealed and removed.

Scam alerts and boost alerts are a system not controlled by staff and are not substantial proof for any sort of punishment.

TL;DR: False history doesn't stay there, because it was never there to begin with.

If you still don't get it, just reply and I'll give you a more blunt explanation.
