At the moment the Altcoin Discussion section is completely lost to spam. I've been meaning to try, and actively report there to try, and save the section however, I haven't got around to that yet. It would be nice if we had a Technical Support in the Altcoin section too. There's just so many threads which could be categorized better for a more efficient viewing of the section, but currently we are stuck with all kinds of posts related to altcoins in the discussion section.
If you want to get some actual serious discussion on altcoin-related threads, it might be better to just post them in the altcoin service discussion boards, if applicable.
That's somewhat of a workaround I've found.
Aside from that, I think it would be more useful to focus on reporting spamming users than to just report threads.
Most of the spammers there have post histories that would be eligible for a ban, I think.
