Forum Moderators: LifeinAsia
He is using false emails to open accounts and I have no way of contacting him other than finding him through tracking his affiliate link back to this forum.
More extreme, if the forum software is available as source, write some code to automatically ban users based on specific text patterns (e.g. in this case you would use the Amazon affiliate code.) Then submit the source code to the author as a proposed enhancement.
But do report him to Amazon (leave a few days popsts to show them)
Also check your control panel - you may be able to block him by IP address - doesn't always work, but it will make life harder for him.
Also, be sure no one can join without a real email address. Keep a list of his, and see if there's a pattern. Then 'premoderate' new members for a while.
Chances are, this is a stalker - no standard forum spammer would bother (unless you are leaving his links intact).
Can you install "nofollow"?
Good Luck :)
