Anybody else have trouble getting off of email lists?

I went to freecycle.com to check it out as requested by a friend and signed up, thought it could come in handy at some point… I get over 100 emails everyday from them now for people in my area getting rid of stuff. I have unsubscribed 5 times and STILL continue to get emails, it’s driving me crazy! Anyone else have this problem with them, or know how to make it stop? ( freecycle.com is where ppl go to sale or give away things, and can find places in your area.. thought it was good idea until this started…)
