Affiliate Marketing Secrets

I run a website, on which betting ‘tipsters’ sell tips. The problem I have is that one of my tipsters is being accused of relaying another persons work. I am not sure of whether these allegations are true or false but the guy accusing him said he will be suing my company for IP theft.
I understand the concepts of IP Law and Copyright but am not sure if it applies to this situation. Just so you understand a little, the guy making the accusations has a program which uses data on horses form to rate them with the top rated being at the top and the worst at the bottom. He charges about £35 a month for this information.
He is claiming that up to 85% of my tipsters horses are the same as his ‘top rated’ horses. So is therefore threatening to sue, I was just wondering if there is any scope to what he is saying as to me its 1 horse in a race of say 7, there is always going to be people who tip the same horse?
He said its a breach of his Disclaimer from which part of it states:

I wrote an article for a blog that I’m no longer affiliated with, and the owners of the blog haven’t removed my article at my request. How do I force them to do so?
