There is one user who has 5 accounts with different names. I did leave messages on two and then noticed with his photos he was the same guy only to find out with his photos he has 3 maybe even 4 other account all with the first name but different suffix and different ages. Without the photos you'd never know it was the same person. So, I am wanting to block all of his accounts and honestly feel this person should be removed from mingles as this maybe give him a way to date more than one person at a time but my no means am I accusing him of doing this just looks suspicious.

I think basically you have to block each account. You can click the report button in the bottom of his messages and his profiles. It will then ask you if you want to block him.
