Hello arman,
this is a useless post (at least in this section), thats why I'm going to close this thread.
Furthermore I would really appreciate it, if you only create posts in the right forum section + with the correct format.
I understand, that you may have problems with English, but it is slowly getting too much.
There is no "perfect evidence", but I would recommend you for the last time to download a video capturing program like FRAPS or OBS.
Videos are way better than screenshots. Furthermore (if you didn't do it already -> execute following command ingame : /timestamp).
There is an old saying which everybody should remember:
suspect is innocent until proven guilty
Thats why I/we won't punish someone without CLEAR evidence.
Cheers,
N.Chester
