Whether something is copyright or not, information you post is still considered private domain unless you grant specific access to public domain in writing. It doesn't matter if "oh you posted it on the internet," if it's original material and you're the creator and can prove that, it's yours. The reason it's hard to enforce isn't because of the law, it's because it costs MONEY. An attorney/lawyer is going to run you $300-500/hour and have fun if it's an international company. Most cease and desist letters are sent by the company or individual, not by a legal entity (despite what the letterhead might look like.)
FastBuds has no right to the pictures here; and any pictures uploaded for contests/promotional events belong to AFN (as per the TOU, which everyone agrees to by posting here.) It's honestly never come up before, so it's just been one of those silent things that hasn't been brought up before.
Can we do much about it? Not really. Honestly, if it's on FB, report the post and tell them you're the creator of that particular content they are posting and that they don't have your permission to be reposting your pictures. If they can't furnish proof they have permission, it's possible FB would make a decision to protect it's OWN interests. That's my best suggestion to you, Konopch.
By the way, I noticed Fastbuds took down the one picture I specifically saw you tagged in,
@KonopCh . Either their spies have told them you're mad or someone already reported it lol...
