Recently I've been seeing a lot of edits to the tag wikis, where the body of the tag wiki is just an URL, either to wikipedia, or some documentation. I feel that this kind of wiki is unhelpful, so I usually reject the edit with a custom message, saying something along the Lines of:
A tag wiki should be more than just a link.
But I've been seeing a lot of them, so I want to confirm if my understanding of what a tag wiki is, is correct or not.
I can see that most of these edits are by new users with low reputations. I feel that since a tag edit gives you 2 points, these are just low hanging fruits, and these users might be using it to quickly gain reputation.
So, are we OK with tag wikis being only a single URL?
