Since last week, I've seen many tag wiki edits with copied content getting approved. There are many examples and some of these are:
SE has a restrict policy about copied content AFAIK. Also, one of the reject messages for tag wiki edits says
This edit copies a significant amount of content from an external source. Generic descriptions such as encyclopedia articles and ad copy do not provide useful guidance; try creating something useful to this community specifically, and be sure to attribute the original author. See: How to reference material written by others.
It clearly states that content shouldn't be copied and the general descriptions such as encyclopedia articles don't provide useful guidance. Therefore, those edit suggestions must not be approved. I've rejected all of them, but they are still getting approved. This approval just making those users who suggested tag wiki edits copy and paste more content.
There is a post on main meta site that says
However, note that content copied straight from Wikipedia rarely makes a good tag wiki. Tag wikis are not encyclopedia articles, and defining the subject is not their main purpose.
Why are tag wiki edits with copied content getting approved? As a community, what should be done?
A few months ago, I suggested a tag edit with summary copied from Wiki with a link to Wikipedia. But it was rejected by a moderator saying the same thing. After that, I spent time to write a useful summary in my own words. With these edits getting approved and the responses to this post, I am thinking why spend time to write a useful summary in your own words. I should also use copy-paste from IMDb and Wiki to edit tags.
