It would be great if mods start to do that, but when I see
COINSBIT ANN thread, somehow I don't think that will happen. Coinsbit is proven scam, having Flags Type 1, Type 2 and Type 3 active, both you and @Jollygood (and a few others) were tagging their accounts. According to
https://loyce.club/archive/topics/518/5185065.html more than 500 posts have been deleted from that thread (archive shows 3965 while there are 3411 at the moment). It's obvious to everyone what is going there and despite all that, thread is still there. I did the same in some threads, reporting hundreds of posts and getting them deletes, but nothing happened. True, I haven't tried this approach, trying to get them deleted as I though I don't have evidence strong enough to do that. At least not in most cases.
I just know that sometimes threads are deleted if pretty much every single comment in them is mindless spam and there isn't any organic activity going on within it. With the Coinsbit spammers, at least they post information about the exchange, like updates and such. Threads just full of comments like "when moon sir" are more ripe for deletion by mods.
