Affiliate Marketing Secrets

I have a FB profile page and there is a random fanpage which I havent even ‘liked’ posting on my wall ALL the time! How can I stop them and ban them from posting and spamming my wall? I can’t remove the posts, apparently I’m ‘tagged’ in stupid photos but they have so many photos I can’t find where I have been tagged to remove it.
I can’t figure out how to ban them specifically in my account settings – although I presume there is an option. I tried to select them in the ‘block’ list but FB kept saying the fanpage could not be found, so I presume it only works for profiles.
One of the worst parts is – I can’t see it when I’m logged in! A friend told me when they where viewing my profile that this person/fanpage was spamming my wall. When I’m logged in the ‘I am tagged in this photo’ doesn’t even show for me.
Apart from spamming everyones wall in this niche (not just mine) the business has a fairly legit looking fanpage, I don’t think reporting to FB will save me on this one – or be the fast action I’m looking for in preventing it (I will be reporting them if I can ever see the option)
Please help!
