On other forums I frequent, there are certain "privileges" that are not accessible to new members. For example, one forum requires you to have a certain amount of posts before being allowed to PM. Perhaps placing a cap on the tag function at say, 500 posts or so may curb the BS. I think it's safe to say that those that are using the tag feature as it was intended have been here awhile, while the shitbirds screwing things up are new. Maybe not...

Then again, if the capability to ID those who are abusing the feature has been worked out it may be a moot point.
