This is definitely the worst spam I've seen; the forum is swamped.
Spoke too soon ! Perhaps low rep accounts should be limited to only be able to start one thread per day and limit the rate of posts they can make to one per 10 minutes, or something similar? I dunno - I don't have a monopoly on good ideas - but this just reacting to the spam makes this forum seem a bit behind the times compared to many others...
Sounds like a good idea. Somehow hackers always find a way though.
