I you have had what you think is a credible death threat, I'd really suggest contacting your local authorities. Occasionally someone online can find someone and they go to crazy extremes, but I don't think it's that often. However, if they know, they can help you.
Also, if it's a member here, please let the mods know about it. They have things they need to do too, such as ban someone who would make such a threat.
And, I'd like to suggest that if you enjoy the site, then don't let a crazy person drive you away from it. Just make another account. Let the mods know so that they know you have two accounts from the same email or however they check it. The crazy person wouldn't know it was you, and you could go on about your business here.
I hope things work out for you.
