Ok so, please, I need your help. A guy emailed me wanting to buy my domain, he made a ridiculously high offer so I was skeptical. Long story short.. I asked him to make a decision before the end of the day, he replied "Oh I'm interested but I'm not going to buy it just obtain it off you xx" Now I'm freaking out. I don't have private Whois or nothing, he has access to all my details, address etc. I haven't taken any security precautions AT ALL. Can somebody point me in the right direction of how to deal with this? I'm begging you.
