If you were banned from MD, you were probably acting like a dick, not exercising your non-existent right to free speech (the MD forum is not the government, you have no "rights" there). If you feel you were unfairly banned, and that you have a legitimate grievance, then say so (as some have), but this whole Getbig vs. MD thing is a crock of shit. Rivalry my ass--they're both good sites in their own way, and MD is still growing... of course it's smaller!
Piling onto the MD-hater bandwagon is an easy way for people to look like they're being tough without actually having to face any real-world conflict. Because, let's face it, what are the chances that MD will actually have you whacked?
