My question involves criminal law for the state of: new york
About a week and a half ago, I was on the craigs list personal section. I came across an ad that said it was from a girl who was "a little younger for craigs list" but did not say how old she was. Since from what ive seen most girls who post on craigs list are in their 20s or at least 18, I assumed it just meant she just turned 18, and underneath the post it said 18. When the person replied, she said she was 15. I said I was not interested. However, a couple days later after she had written back, i asked her if she had any pictures. I did not ask for any nude pictures or sexually explicit pictures. It was stupid, I know... I don't know what I was thinking, I kind of just wanted to see if she was actually 15 or not, because I had honestly never seen or heard of anyone 15 posting on craigs list. The person insisted I give her my phone number. I didnt respond, and the person sent pictures and asked me to send nude pictures of myself and said something like lets go out. At this point i kind of thought something was strange because the person had been repeatedly contacting me and asking me questions like how old I was and what my number was. I asked a couple questions like what part of new york the person was from and how exactly she thought we were supposed to meet and that I wanted to speak to her on the phone before I did anything.
That was basically it. I never said or suggested anything sexual, and I never said I actually wanted to meet the person. The only picture I sent was from my first e-mail... it was just a picture of my face. The person then revealed himself to be a blogger who keeps a blog of "pedophiles" and sent me this a link to this site, on which he placed my e-mail address, my photo, my name, my possible street addresses... and said he was tracing my ip address and was going to send everything to my family, friends, and the police. I asked the person to take me off the site, and he said if I paid him a fine of $400 he would, or else he would send all of my information out to everyone. He said I had til midday to decide.
As much as I know I shouldn't give in to blackmail, I sent the person the money and he informed me that he deleted the e-mail records and has since taken me off the site, and warned me never to talk to an underage girl again. The person has good intentions I guess, but black mail is illegal isn't it? I know it was stupid e-mailing the minor, even if I didnt have any malicious intentions, and it was probably stupid giving into the black mail. My question is... if he lied and kept everything... can I be charged if he some how traces my ip address and shows the police everything? I swear I said NOTHING sexual or inappropriate in the e-mails... I barely said anything at all. I know e-mailing a minor is inappropriate in itself and I regret ever doing it. I have never gotten into trouble for anything and I am really young. Please give me advice, I am really scared.
