Got a misuse of roblox systems ban, what does that actually mean?

it's the catch-all for using the platform in a way it isn't meant to be used - exploit or cheat tools, abusing bugs, botting, using an alt to dodge an earlier ban, that sort of thing. annoyingly the message rarely says which. if you think it's wrong, appeal through roblox support and keep it short and factual. if someone else had your login, say so, and change your password before you do anything else.
