OP, thanks for your information but I think it's long been realized and even some forum contributors have been ignoring gambling board as much as they can afford and that's just as much as they are ignoring altcoin discussion board.
I don't like spam and it made me try to avoid spam posts as best as possible and it also made me decide to report a number of spammers to moderators over the time. I reported a number of spammer profiles and posts to the moderators on the gambling board [some of which were handled good], but from most of those reports I got unsatisfactory results as they were not handled to this day. I have said time and time again that my 100+ reports on the gambling board are not handled regardless of the reason and that made me stop doing it.
I admit that there are a number of signature spammers paid for bitcoin or altcoin who post spam there without good knowledge. Some of them are 100% active there just to avoid post deletion as reported, and this led me to ask one of the moderators how to go about it. I'm sure everything will be resolved on a case by case basis as the moderators also can't delete any user's posts that don't violate the rules even if they disagree. This perspective may have led you to suggest a thread of self-moderation on gambling boards so spammers can be suppressed, I certainly agree but I hope that doesn't prevent anyone from free speech. I like to report spam posts, and for your suggestions I'd also support them in case it's a very urgent matter.
