I registered on poiscenter 2 days ago but have not received confirmation response yet!!! I hope someone will find my mail between all that spam.
Those guys doing all that spam should be tracked and reported to authorities in the same way that paedophiles are taken care of.
Poiscenter is setting up a new anti-spam program, so for now it's not possible to register a new account there on your own.
You can send poiscenter's administrator, Daveman, a private message (his email is listed on the registration form that you can find on the site's registration page. Please include the username that you used in your registration email, as well as your personal email address. He'll be able to search for your registration form and unblock it. You'll then receive an email to let you know that your registration has been approved.
