Alina's message suggests that she has reported it. One of the drawbacks of having a forum that's open 24 hours is that it can't be attended at all times.
There seem to be around 16ish posts from each of 8 spammer names. You can actually get rid of them all by 'ignoring' the culprits. They are these names:
That does restore the apperance of the forum.
It shouldn't be hard for techy people to delete those spammer names, and their posts.
I wonder what can be done to prevent it from happening again, every night. These people have no scruples. TBH I find spam a real pain in the neck. I have filters on my Email, but they are not 100% effective, so some rubbish still gets through, and there's always a chance that something legitimate gets sent to spam, and is missed.
Perhaps we should be grateful that the products being advertised last night are only watches and similar.
