I am confirming this, but it is more than likely because some users exercised close votes, and chose a custom off-topic reason.  This was the **WRONG** thing to do with this.

When you encounter spam on the site, the procedure is to

 1. Flag it as spam

The spam flag is special.  That is all that is needed.

Please 

 - **DO NOT** cast a close vote
 - **DO NOT** flag any reason other than spam
 - **DO NOT** [edit the spamminess away][1]
 - **DO NOT** [edit the links out][2]
 - **DO NOT** [cast an additional downvote][3].

Just flag it as spam and go on your way.
