No there aren't. It must be that the ROBLOX filter saw it as against Terms and service on the website or it could be a admin troller.
The admins on ROBLOX really don't look deep into things and are quite soft. They ban anyone and will ban anyone for random reasons.
Sometimes, people do get banned for no reason or for nothing. However, most bans are reasonable. If you got banned for no reason, please contact roblox to see what, and you could just make a new account.
You get ban because you broke a rule like Scaming
Got banned from someone else being an absolute jerk
