After resisting for many years, I joined classmates.com because they emailed me that 25 people had visited my profile and I was curious who they were because frankly I doubt I spoke to 25 different people while I was in HS. After joining and finding 3 names I recognized and 20+ I didn't, I emailed some of them and they unanimously indicated they never visited my profile and/or never knew me. I'll be cancelling my membership soon.
