after 10 days or something. looking at the report for the reason of the ban, you were advertising when you where told to quit it, and ignored it.
The 4 day ban from the forum is because you made short posts that counted as spam ...again, and ignoring the warnings in the SB.
As i told you so many times, the more you break the rules, the more extended bans you get. In your case, you are breaking the same rules over and over again. The purpose of a warning is to let you know that you are doing something wrong and to give members a chance to adjust theirselfs. However, it seems you ignore it, you already recieved so many chances, thats why your bans keep being expended.
So do yourself a favor and behave yourself and obey the rules.
