I believe there should be a warning to people if they send 3 or more messages at a time. This way, no one can spam peoples inboxes, or spam the main chat. And if they continue, it's a kick, then a ban.
Not only that, but I'd also like to point out the fact of cussing. People usually get around the filter by just saying the letter multiple times. For example "wwwwwoooorrrdddd" I was wondering if this will be fixed in the filter update? If not, it's really a big problem. Like I said, you guys could just make it so that people cant type 3 letters repeatedly
