I've recently been BOS on OldCP right after being warned by Sled but that's ok, but I've been banned on Forums for this:

Bos on OldCP
20 days

I haven't done anything on the forums check all my posts or deleted ones legit I've not done anything wrong on forums this place is my castle..

Hey frogs, unfortunately after your apology you continued to be rude to others on oldcp and also made a rude post directed to a user on the forums (and there were reports of you spam disliking posts according to other mods). Also since you're BOS on OldCP this means you are also BOS on all other parts of the community. This was a decision made by the admins too, since you continued to break the rules and be rude to others even after being warned and BOS a number of times.

The reason why you get banned without warnings is because you already know the rules so what's the point of warning you for a rule you've broken many times before?

Unfortunately at this time you have to wait out your BOS time, I don't think mods or admins are willing to hear another apology and then see the same actions over and over again.
