User management

I’m hoping there’s a plugin that does this that I simply haven’t found yet.

One of my installations has a little over 9,000 registered users with about 20-30 new every day. About once a week I go through and search for things that would lead me to believe users were fake such as “spam”, cuss words, etc. I’ve disallowed email registration from all the known mailinator-like services as well.

The problem is that there’s no way to tell if a user has ever logged in, so I don’t know how many of those users are “real”. The user_status field serves no purpose (One would think it would tell you who is an admin, a user, not registered, etc.) and there’s no record of a users last login date – some very basic features.

I’m assuming there is no way to resolve this retroactively, but anyone know of a solution I can use from here on out?
