I too would love to "reclaim" Bitcoin Discussion. I barely go there now, and thus don't report posts there. Unlike the altcoin board (where I report many posts like "great project" from automated searches), Bitcoin Discussion has much more "generic shitposts". If ever a cleanup starts, and the board gets one or more dedicated Mods, I'm willing to do my share to start a massive cleanup.
I'm also interested in a massive cleanup in Bitcoin Discussion.
What I would like to achieve is to have a lot's of topics deleted, because spammers and bounty hunters would only care about the post count, and you can only decrease their post count effectively (not one by one) if you delete spam megathreads and those where they only post average meaningless replies.
I know that we surely will lose some decent replies too, but if this is the price we have to pay for a clean section, I won't be too worried about it...
Or, we could ask for a development, not to let the merited (but just the merited) posts to delete from a thread, so if you delete a spam megathread which contain some merited good quality posts (I know the chance for that...) they will remain and the topic can live on with the quality posts.
