Ok. As for the rank thing. You have to wait for a map change to start on your own rank again. This is because when you first join the server your IP is not the same as last time due to a dynamic IP. After a map change you should be good. Suiciding is illegal dont do that, reconnecting will make you wait longer, restarting CSS will take twice as long, and killing and getting killed does nothing. Just wait for a map change.

As for the mean players, its a new thing, zm isnt about teamwork anymore as it was a while ago, now its like everyman for themselves. Especially on escape maps, so I hate sayin it but your on your own in that category. But as for mean players disrespecting other players admins should stop that, if no admins are present contact one on steam.
