Compare it to LinkedIn’s TOS/Privacy Policy.

There’s a couple of points I think are getting over-looked:

1) You cannot see what your privacy settings might be until you register and agree to the TOS
2) They’re not responsible for what recruiters / third parties do with your resume or email address
3) If you cancel your account it’s “marked as deleted” in their database. Not deleted. Marked as such. Got it? Good.
4) If they sell your information, they’re not responsible for anything that happens to it downstream; the only way you can get off of those mailing lists, etc. is to contact whomever they sell to, and whomever they sell to, and so on and so forth. Plus, those people may all have “cached” versions of your information, so if they get a data snapshot of NU today, you cancel tomorrow and they get a new snapshot and sell it–guess what? Those companies will do a merge to remove duplicates–they’re not going to go out of their way and REMOVE you unless you know how to track them down.

There’s money in the list they’re generating.

5) Yep, it’s easy to use that LinkedIn slurp they’ve got set up for you. And, of course, all of your information that is respected and protected at LinkedIn… Well, different set of rules now.

Pay attention to the TOS and decide if giving up your information is really worth it.
