If you go historically at least, the more nationalist Marcus Garvey did associate and collaborate with the KKK because they shared views of racial seperatism, as opposed to the "less nationalist" W.E.B. DuBois who believed in racial harmony and condemned cooperation with the KKK.
I do doubt that's what most of them are getting at, thoguh
As someone who's worked as a sysadmin, banning you for this would be an unbelievable level of shittiness of the parts of the admins, if anything you should be sending them a bill for your unpaid QA hours. I kid, I kid of course. But seriously, endusers are constantly doing stupid shit that breaks sites (And then do it again, and again, and again, after each time its fixed because "it didn't work the first time" ) and never file a bug report or probably even know what a "bug report" is. I seriously probably woulda cried tears of joy if I came across someone not only giving a heads up of even "hey, this thing I tried to do didn't work and now your site is broken", but also being able to explain exactly what they were doing and how it caused it to break.
