Roblox has recently been taking FastFlags more seriously, which has led to people getting banned from Roblox for using FastFlags.
Only some FastFlags are safe to use, I have tested my FastFlags, and they are safe to use, but I strongly recommend not using other FastFlags, unless you know what you are doing.
Therefore, I am not responsible for any bans or actions taken on your account by Roblox, use FastFlags at your own risk.
