You need to change the way that your forum does topic notification, namly you need to verify that the person at that email WANTS the email and was not signed up by someone else. This is a form of reflective DoS attack and you could be legally liable for any damage, basically FIX YOUR FUCKING FORUM.

I do not ever want to see another email from this board, EVER.

damn dude have a drink and chill just have it sent to you spam or junk folder that way you dont have to even look at it

moron isn't smart enough to contact staff and give us his email to have it removed.. guess he'll enjoy more spam.

pm me and I'll look into removing your email.
