What is the difference between accounts and users tags?

Question

With 26 questions tagged accounts, 19 questions tagged users and 4 questions tagged users+accounts it is unclear to me when to use which.

Should these two tags be merged? Or, if not, how should their tag-wikis be updated, so their use cases would be distinct and clear.

Answer 1

accounts should be for questions involving services that offer accounts, such as iTunes.
users should be for questions involving user accounts, such as those on OS X.

As neither has a wiki, it's unsurprising that people have gotten confused. It's cleanup time!
