Allow a censored word for a specific user group?

Thanks.

Here is what happen and maybe there is a better way to go about this.

I had to block imgur because some people were posting what adsense deemed as proavactive pics. Well my board has over 2 million posts and I could not go through all of those so I was wanting only specific user groups to be able to use the imgur. So basically I censored imgur but nobody can use it now.
