It seems we can achieve a consensus on a certain set of tags this time without reading too much into things. Let's clean up sentence-related tags. I just came up with a few ideas, and I present them in separate meta posts so we could discuss each of them.
Proposal: Blacklist sentences
It's a completely redundant tag and serves no purpose on the questions it's on. It's a meta tag, and meta tags have proven to be useful on ELL sometimes. This one is clearly not useful since all of the questions it's on either belong to syntax or don't need the tag at all. I don't want it to come back. We're much better off blacklisting it.
What do you think?
