I banned him based on these facts below:
-Multiple bans under his IP (Explained below)
-Multiple bans on ACTIVE BANS section
-No EXPIRED BANS under his ID. (Explained below)
If there is a dynamic ip, 11.11.11.12 , it changes to 11.11.11.32 or 11.11.11.76 . But only the last digit changes, so, if i search for any bans under 11.11.11.12 there wont be shown any, but if I search for 11.11.11 there are bans shown. This is what I did with molat. I saw multiple bans under his ip, then i searched for bans on his ID. We all know that old users have been banned once, so there must be an expired ban of him. And there wasnt any, which made me think hes faking IDs. I also did a research on his ID, and found that it was a steam user. As we all know, steam users have an avatar along with their name in scoreboard, but molat didnt have any. Then i searched for his name on banlist, and there were 4 bans, 1 WH and others banevading.
Based on these facts, I took the decision to ban him using his ip.
