WordPress sites removed

Hello,
Any guys here have some advise, I had a long standing blog I was running on wordpress for about 2 years suddenly removed apparently it was reported as spam, there was no way this was so I write informative content on many blogs and am an active member on many forums. I run my own dating network with a very popular site [link to non-wp site removed] many times I have competition trying all sorts of tricks to remove my sites from search positions, actually I never realised the industry was full of so many bad people.
Is there any way I can protect by blogs from any malicious attacks or reports. ?
I only ever use unique content and images I own the copyrights to.
