Facebook, how do I stop someone from seeing my comments.?

[Jimmy]

I have a particular friend on Facebook, who has started trolling a lot. Whenever I make a comment on group pages, he follows up just about everything with something annoying.
I added him to the restricted list, but that didn't work. Other than un-friending him, is there anything I can do to block him from seeing my comments on group pages?
Note: These are pages he is not a member of, so he would not be there normally.

turn your facebook privacy to "only me".
go to Settings>privacy settings and do what you want.....

BLOCK HIM and he will not see you anywhere on FB. Even if he tries looking for you, he will not find you. When you post something on someone else page, of comment on something. He will see everyone's comment or post except yours. It will be as if you were invisible. LOL

Its so simple , go to the privacy setting and make a custom setting of your profile , you can block them who interrupted in your comments.

well there is one thing you could do, you can delete him or block him so he will never add you again, but if you don't want to you can make his comment's as spam or delete them
