Yes, there's definitely something amiss there... Some of these spammers have been allowed to post ~ 200 times under the same user ID with no action taken, plus they're using multiple IDs...How can the spammers automatically inject into the forum multiple spam emails, yet reporting spam requires a cooling off period between each report.
They may have been viewed by others who might have reported them too, or maybe they've been accessed by web-bots.I noted that most messages seem to have been read by at least three people, it would be interesting to see if they were the same three (beyond OCD) I can't forsee any person reading all the spam messages when they all look the same
We're on it, but it's a lot to deal with at the moment.
It should be cleaned up shortly.
