Forum:Are people allowed to advertise their stuff like this?

On the wiki that I admin for someone posted a blog post advertising for (Spam link added to blacklist). I was wondering if this is allowed as it seems that he is trying to get free advertising. I thought I should check if this is allowed or not before banning him. The blog post in question is here. Thanks in advance for the help.

 * Looks like a spam bot to me, since it did the same thing on one of the wikis I edit. I removed the blog post and moved on. — Sovq 09:21, August 12, 2011 (UTC)
 * There are some porno ads advertised controversially on some Wikia wikis. Should we revoke them to avoid offense? 112.202.66.167 06:27, August 13, 2011 (UTC)
 * They'd be against the Terms of Use, yes --  Random Time  06:28, August 13, 2011 (UTC)
