My inbox is filled to the brim with your reports. This has helped us greatly in effectively removing spam posts, some of which were very icky.
However, these measures are no longer cutting it, and so I actually had to use my head for something other than a paper weight.

I've altered the rules on what freshly signed up users can do.
The idea is that all new users will have their posts validated by moderators,
so the spam may be posted but you will no longer see it.
If you notice anything strange, like not being able to post for some reason, please let us know ASAP.
Thank you for your attention, carry on.
