Ok so i recorded a demo, my mouse get fucked when those players push any "sentence" bind : A, Bozo, Husler, Crashy, jado.For some others iam not sure.

So they have 2 possibilities :

1) its some console command, so i would like to get the server's logs for check, and if anyone more skilled for read those log can take a look too that can be cool.
Games was played : Tuesday 26 march beetween 7.30pm to 8.44 pm.
Btw checking also the last 2 weeks server's log can be usefull for check wich files was on it.

I also remember long time ago jado asked me to reconnect on ffa or ctf server (dont remember) without any reason.And since this moment those mouse problem appear.So maybe it can be a kind of hack.If that it, this hack was upload on the game server, and constitute an illegal action and will be warn to some authorities if this case is confirm.
I already pay attention to that on another game (killing floor), my mouse wheel mouved alone, and switch the weapon.You can see that on the demo, it switch alone to plasma (mousewheel up bind for me).So i think more that is this case.

Here is the demo, dunno if you can see my mouse get fucked.But just pay attention to the angle of the straff, it become lower when mouse is fucked.Also look how A suddenly wanted to leave the game, and how nobody wanted to push again a sound bind at the end.When finaly crashy did that, mouse go back to normal.And btw each time a sound bind was pushed mouse was fucked.
