I have a Joomla 1.5 site with Ninjaboard and have noticed spurious unwanted postings from Poland etc when I create a test post you see postings appear at the bottom of the page in foreign language. I get random users creating accounts and I think they are adding "invisible" posts to my website probably as some sort of under hand SEO activity. Where does Ninjaboard store it's posts so I can go have a look and clean it up. Will installing spam fighter help against the types of postings.
Trouble is you can't see the postings when you access the forum through the normal methods, but you know these people are getting in an adding content somehow.
TIA for any help.
