There's less spam (and much less posts in general). In the past week,
35,000 posts were made.
4 years ago, there were 280,000 posts per week (that's 8 times more).
Wow, that's a dramatic difference. Were there more bounties/sig campaigns available then, or was it just that the market was much more bullish then than now?
It's been a long time since I've actually read through threads in sections like Bitcoin Discussion (which has been a magnet for shitposters ever since I've been a member), but I can totally see how low-value posts could have dropped in the past few years; there don't seem to be as many in sections like Economics and Meta, and it's likely a forum-wide phenomenon.
But what happens the next time crypto heats up and bitcointalk once again starts attracting all of the illiterate spammers who want to enroll as many alts as possible into bounties? We'll probably exceed 280k posts/week and you better believe at least 80% of them are going to be complete crapola. I like OP's suggestion, but I doubt the boss is going to go for it.
