On of my friends (CoolBassPlayer) tried logging onto minetime and it said she was banned. She has never used hacks,lag items,griefed, or anything of that sort. If you know why/how she got banned or how to resolve this problem please let me know.
Yeah u can get banned if u try to advertise a server or even say a string of numbers, or if u spam chat too often
You cannot get banned for saying numbers or "spamming" unless it really looks like a legitimate IP. You may, however, get kicked by the console for advertising/spam. The only way you get banned for advertising is if a staff member catches you doing it or if you get reported for it, either way we can judge if it is legitimate or not then. The chat filter cannot ban you.
