On our server the official Server-rules shall be followed.
Read them carefully. Causing lags for other players (=griefing) is not allowed.
You threw the smokebombs "for fun" => for your fun, since you seem to enjoy to cause problems for other people. This was obviously what you intended when you threw them.
I never said you threw them into/at teammates. You threw them in the middle of the battlefield, trying to cause lags for everyone.
I also could ban you from our server, but I do not want to do that yet, since there is a little hope that you soon grow some hair and start playing serious and fair. Once in a while one of you comes and plays with us, without behaving like a pubescent child. So not all apples of that tree are rotten.
don't use particle systems
not relevant here at all.
The situation with the smokebombs is not the mainpart of my complaint. It is just _another_ point to show their behavior.
