My rule is probably yours. When I get an unsolicited email from someone, I google them. I was emailed this:
We are DIRECTORIA, we'd like to let you know that we have listed alhawke.com on our directory (for free).
If you want to remove it click here: "a link was provided"
If you want to make any changes, please, "a link was provided"
I can't look them up because if I click the link it could lead me to a virus. Should I just completely ignore? Or does any of you know what this is about. It'd be nice to remove if I want but I don't dare click on their site without knowing who the $#*% they are.

(I'm advertising my website through google so that's probably where the source found my website).
