I can understand why you would find this annoying, but you just showed yourself to be an arrogant twat with claiming that you have the right to do whatever you want on our TS server, that disappoints me.
We were in no way attacking you for inviting your friends over, we just decided to take actions on your friends' provocations. Now you come complaining and not doing much better yourself.
BlackIntel is a community, that expect members to communicate with each other and ingage in social activities, like games. If someone unknown to the community enters it is common, at least in a lot of cultures, that one introduces himself, is polite and adjusts him or herself to the current standards of that community. If your friends come in here ignoring whoever put time in this community, is it then a weird action from us to kick them out?
Personally I think that makes sense, but please, if you feel differently try to explain.
