c) Associate your real email address with your FB account

Facebook gets an email address I don't use anywhere else. No one has me listed in their contacts under the only email address facebook knows for me (well, I presume. It's not hard to guess the address I use for facebook if you know my real address, but there's no good reason anyone but facebook would use it).

I've done that on general principle for more than a decade any time I have to give my email address to anyone other than an individual. This instance is the first time in a while where it's actually felt worthwhile. Originally I did it more for spam tracking. GMail's excellent spam filter fixed that problem for me years ago. But I never stopped doing it.
