Zippy is very correct. Here is the full story. The server was lagging a lot with all players getting at least 250 ping. It crashed soon after this, so I checked the logs. And I was greeted with a huge number props being spawned in by you. I then proceeded to ban you for propspam once the server had come back online.
Also, in your story, you say that you may have clicked your autoclicker button by accident. This is all very well, but what I can't quite understand is how you also manage to hold the 'Q' button down whilst playing on Fifa? To be honest that seems a little unrealistic to me.
