Omgosh. Dude, that is rough. The humiliation thing has snuck up on me too recently. Two thumbs down to that crap. I'm very sorry that happened to you, those people sound evil as hell to do that to you.
Well my scariest experience was because of porn. Half a year ago when i was really deep into the Sp fetish i got a mail that someone in china had logged into my account and it just gave me extreme panic attacks because i was so scared that all that stuff i had been watching and posting would be exposed somehow. Eventually i found out it was just a spam mail but it looked pretty real and for about 2 to 3 weeks i got panic attacks almost everyday. Its one of the reasons i am now trying to quit completely since i never want to go through something like that again.
