I didn't realize mods actually did that (checking a member's post history), because although I've taken a break from post reporting, there was a time when I reported TONS of shitposts, and that's exactly what I was doing, going through a given member's history and reporting shitposts.  They're like roaches--when you see one, there's usually a whole colony of them hiding out.  This is good info to know.

Hilariousandco is a good mod and I know he appreciates reported posts.  Unfortunately as much as he cares about the sections he moderates, he has a near-impossible task.  Bitcoin Discussion is just crawling floor-to-ceiling with spammers, and my impression has always been that Theymos limits what he can do as far as deleting posts and banning spammers.

Regardless, keep reporting garbage as you find it.  Sometimes it may feel like your actions are in vain, but it a person has a low enough post quality, action will eventually be taken.
