There are endless discussions about these situations in the "Feedback" forum.
I think it's fair to say that the site's Admin has made it persistently, unmistakably clear for years, now, that he has absolutely no intention of taking any action about it.
If you report individual posts like that, sometimes the moderators will "hide" them (with a little link that says "click here to read the hidden content", or whatever the wording is, which of course actually draws attention to it!), but not remove them, and not stop the members concerned from doing it for ever.
And that's exactly what they do.
We all know it makes a mockery of the forum, but that's how it is, and apparently that's how it's staying.
The change of policy and procedure required for them to change that is too much for them to contemplate, I think.
I think they genuinely don't believe that this is such a big part of the cause of their loss of traffic, etc. etc.
We've been over this loads of times.
I've been saying it both in public and in private since I arrived.
It obviously isn't going to change. And that's Pipstradamus's right, after all. It's his business!
