The terms and rules are crystal clear that we the users have no leg to stand on when it comes to how the forum operates.
It would be very easy for a moderator to log on, delete the spam posts, every couple of days. There's very little traffic here. I have no sympathy for the site's owner when this spammer gets free advertising.
On the other hand, these software products can't be real, I suspect someone is doing a psychology experiment.
Just my opinion.
