Watching with regret that the same group of users are bumping the thread with the same garbage. Other day I reported the tread by requesting to lock it to the mod but no response yet.
Not getting a response to your report is a kind of response itself, when you think about it. All you can do is to report posts and that's about it. In some cases they stop with spamming when enough posts get deleted.
I am not sure if there is a rule about creating fake conversations by the same group for the sole purpose of bumping threads. But if not, that should be added. If an entire thread page is covered with posts of the same group of users and that same group dominates the entire thread with unnecessary comments, admins should react to it.
Unfortunately there is no rule against that. Some time ago I
started thread here in Meta asking can those threads with no real conversations and basically only paid shill be removed, but I never got an answer.. If you check that thread you will see few examples of completely useless and spam filled threads that I reported and of course my reports stayed unhandled.
The only way to get thread removed (from my experience) is if you get a solid
written proof that users are indeed getting paid to write on thread. In most cases it happens when some altcoin project organizes airdrop and set comment as one of the requirements and of course published that rule on website/Telegram group. In my opinion it should be extended to bumping services as its pretty obvious to everyone what is going on.
