It depends who you're banned by.

If you're banned by Lulu, you probably pissed alot of people off or said something really offensive. You probably did something to earn a legitimate banning.

If you're banned by Hunny, you're probably under the age limit she made up for a cannabis website.

If you're banned by Del..., you probably said something that he didn't like. Or you have a conflicting opinion with him. Or maybe you just made a non-sense post while you were stoned.
