I might be wrong here, but what if I change my settings to "not show the last seen status"? I guess in that case this doesn't work. Yes, I believe checking "Online" status frequently does give some information about my activity. Correct me if I'm wrong here.

I was thinking the same. I haven't seen any of my friend with last seen status enabled.

If you disable on your account, you can't see the last seen status of your friends, even if they have it enabled.
