There was a game I just joined and eveyone was a noname omg im turning into a noname zombie too many nonames

Honestly, Z, you should get rid of name changing. There'll be a DECREASING number of no names instead of INCREASING. It'll make lote of players happy. Maybe leave the option, but your request has to be reveiwed by you or q mod, or someone that you trust to not screw up.

But people can still make multiple accounts.

I think Zuperman should make it alpha-numeric, minimum of 3 letters. That way you get a decent name and no invisible unicode characters.

yeah, or say, ban everything that isnt displayable, so that legitament names with a normal charachter in it would be allowed, for example, the Engima tag.

And in names as short as or shorter than the lower limit (I personally like 4), replace ".", "(space)", "_", ",", "'", "¤", etc. with an "X".

Yeah. Alphanumeric, 3-4 character ftw.
