I saw it differently: a potential spammer "obviously" made a reservation post in a popular thread to add a link later (by editing), when the post sinks and nobody will notice.
It wasn't a violation yet, so I didn't report it and had to return the next day: there was the poll! It would've been too annoying to watch that post otherwise. And then/now it's gone.
So it's not about numerous reports, it's really useful regarding unreported advances: I've just reported a recurring thread crapper who apparently works on it's counts, gets banned (I don't know what for: PMs?) but the crap remains uncleared.
No current "misbehavior" except for obvious(?) self-appreciation from another account.
