please why ?

you mean how many people have been banned, or most times a person has been banned?

this is a very vague question, can you be more specific?

Do you mean the types of bans, the messages that show up during IP bans, or ban reasons?

If you're asking how many bans there are, I don't think we can answer that question. The Scratch Team might be able to share some data, but I wouldn't guarantee that.

If you're asking about how many kinds of bans there are, you can look at this Scratch Wiki page. Mutes are kind of similar to bans in a way, so you can learn more about them by clicking on this link as well.
