I have two Facebook accounts. The one I stay logged on with uses a pseudonym; I'm not connected with anyone I know in real life, and I use it to participate in certain Facebook groups (as bad as it is, it's still probably one of the best places to look for active web groups).

The other is my old account. I've removed any photos, changed my last name, and check in using a private window (since I don't log out of my pseudonym account) about once a week to see if any friend's messaged me there. If they didn't, I close the private window and I'm out.
