lol... lol... it was Alex23 and Josh. Did you check out Mrsmuscles' posts in other threads? where they weren't pretending to be Junior? who else uses "relax chief, it's not that serious"? Too bad those posts are gone by now.
So the of/off confusion can be mimicked, but not "Relax, Chief?" The early posts from that account don't read like his, granted, but the recent poster who got TOed was clearly Junior.
He was PMing me during the debacle, with all the expected tells: stunted grammar, delusional bravado, off/of silliness, etc. Junior, no-brainer.
