I guess you didn't play on any normal NQ server lately. Most of the server which are running NQ have restriction rules like No spawnkilling / No spawncamping and or using heavy weapons at CP or Flag is not allowed.
Spam is really a funny subject.
Why claiming there is more spam in NQ than other mods with typed text, voice chat and/or !commands which you probably aiming on?
Besides what is spam for you? The meaning of spam in the world of ET is kinda different than the global meaning in normal life. So that comes up with, there are no global accepted restriction about spam in ET. If you you say v54 twice, is that counted as spam for you? If you want you can restrict from server side with spam protection.
But i try to base your opinion; Maybe its because of the fact that NQ has more custom servers with add ons like sound packs. Maybe this feels like there is more spam. But again its your interpretation of the rule. At least i can say they enjoy having custom commands and voice chats and don't hear any regular player complaining when its being used normally. It can happen that some new players doesn't know the rules, but by showing !rules as command (in 10 different languages) they know it and/or can be warned once for it. After that they know it and its all fine.
With your explanation it feels like your saying that the players on Noquarter are behaving with evil intentions and there is no fun to play it. But in fact the players are behaving proper and there is a lot of fun while playing the game on NQ. At last; What is "more shit". Don't get me wrong, if there is something which can i can improve for a better game play and gaming experience on my server please explain it with more words than you did.
Kind regards,
