I think this is a great idea.if you like the user and add them that will give them the privilege to comment you.But if you don't add them you can't comment them.What I'm trying to say is that you can only receive comments from people you like.If you see a user cursing at everyone you don't add them.Then that way you don't have to put up with their cursing.
Yep you are exactly right my friend. Everyone would block spammers until they won't comment anything only games and forums but then they will be reported in a second
Advertising, soliciting, heck even peddling, those count as spam. You can definitely tell if they were new here, they would instead post on the forums, they wouldn't know how to post on someone's profile the day they joined.
I like the concept, but I would suggest this modification. Instead of putting the people allowed to comment, why not have a "blocked" list. Thats where you ad a user that you don't want to be able to comment. Lets say a person is mean to you, or just spams, you add his user name to the block list, and he can never comment to you.
I think thats a better idea to this concept. Kind of like a spam filter
I like the idea I can keep my page spam free yay spam on my page more than 3 times bam your blocked for spamming.This has been suggested more than once it will be suggested again but I don't think it will happen but its a good idea.
