I don't think you can get in trouble for posting non-furry things.

you should be fine as far as the non furry stuff goes, I honestly don't know how the rules go anymore they seem to pick and choose when to enforce them and when not to from what I've seen

and those BBs give me the impression you'd probably get along with my kid brother he's got like 5 or 6 guns, 5 of them are just air soft a few pistols and a couple of rifles, the 6th is a real gun that he fires at the range with his dad ... bit dangerous for a kid his age if you ask me but not my call
