"Noob" "E/Z" "Lagger" - These are all insults I get on a daily basis, And that feeling that you get when someone calls you "E/z" after killing you, why do we get that sort of feeling? Like seeking vengeance? I once stalked this guy through the lobby, killed his whole team (Team SkyWars) just for him to call me a "Noob" "Lagger" once again.
If they're made punishable, that's a bit too far, but once again filtering them would make it just easily avoidable by typing extra characters in like "N00p" or "Nuub".
Punishing it would be a better option. I don't really know whether to agree or disagree on this; it's just like a small percent of Cubecraft Scum decide to ruin other's days. (Also, staff receive the most abuse, better train your PvP skills)
About that "Lagger" part, can't really do much since I'm from India and the connection to Cube sucks, I have 100Mbp/s speed and still can't go below 100ms.
