Continuing the discussion from Remove server anti-cheat server promotions temporarily until 1.4.4.9 is no longer relavant:
So typing the server version, 1.4.4.9 can get you banned. Similar goes to the case of IP addresses. 1.9.9.9 also meets this requirement. Is there a way the filter can be configured so that it no longer bans people for saying the server version/1.9.9.9/1.x.x.x? As they are server numbers but in IP address format. I made a video to demonstrate this.
