That's a good catch bro and I don't know what's the reason why they bum old threads even though they already know the forum rules.
It's rather simple really. His signature campaign requires posts to be made in the gambling boards
It's not far from this and most times doesn't end in the ambling boards but a lot of other boards on the forum too. Though, I do feel there are some unaware newbies that effortlessly bump these dead horse threads with hopes to revive it. One thing that marvels me is how, though they don't seem to be conscious of the rule and still claims not to have seen the caption in red that emphatically warns on the possibility of bumping an old thread.
Perhaps some threads should, threads like use of the trust system by LoyceV, bitcointalk or crypto terminologies of some sort, etc. Threads that deals directly in the forum and can't be stressed enough in the crypto space. Otherwise, the case should be left to lay low.
