I've recently noticed, by one user in particular, a rash of tag wiki updates where the text is copied verbatim from either Wikipedia, documentation or another website. Some examples are below:
In some cases, the tag wikis were approved without anyone noticing the copy-and-paste approach.
When we see something like this, what is the best approach to take? Clear out the tag wikis of approved tags? Notify a moderator so they can talk with the user? Something else?
