Suggestion: Choose who wants to write in your wall and block who I don't want to write in my wall.

Question

I don't know if this suggestion has already asked.

For example, I like to some people to write in my Wall but there are some that I don't like.
Can Pokemondb has a button at the user's page for don't allow that user for don't write in my Wall. This can very effective against spammers.

Comments

So basically a wall blacklist?

I see where this is coming from, but I don't think it would be that valuable of a decision. Js.
