Filter users where Last Activity = Registration Date

For various reasons, it would be useful if I could somehow filter users where their last activity was on their registration date.

i.e. I basically want to know when a user signed up, tuned in, dropped out - never to return.

That way I could target them for an email campaign, create some metrics based on that scenario, or monitor them as potential spammers.

Currently, there’s no way to filter like this, unless I use the API and write some scripts to do it.

I think it would help towards this idea, too:
