It is only a 10min ban this was in the logs:
L 01/20/2013 - 17:34:16: [plmenu.amxx] Ban: "whoisthis<2204><STEAM_0:1:31449742><>" ban and kick "dreaM! * Rem0ver<2242><STEAM_0:0:8716740><>" (minutes "10")
There is no reason given as this was through amxmodmenu bans.
its dd2 admin accept.
As for temp bans we can use amxmod bans there is no option to show the reason..
As the reasons can be following: swear, language, admin abuse, etc
Sure only after a warning..
