From the KLOV noobie thread.
Due to ongoing issues with trolls, spammers, thieves, and other undesirables, we have changed the process for allowing new users onto the forums.
For about 6 weeks now, all new signups have required either (1) a $2+ paypal donation to the International Arcade Museum Library, Inc. (tax deductible), or (2) simply the recommendation of an existing forum member.
(1) It's easy for trolls and spammers to create infinite free anonymous email addresses, it's a tad bit harder to be anonymous when you have to have a PayPal account.
(2) We've had several new members who asked an existing member to vouch for them and overall this process has gone smoothly (the existing member has had to PM/email me). We just made it simpler today though.
Now, from the VAPS menu, there is a link logged in VAPS members see called 'Forum Upgrades', with which a VAPS member can approve any new forum member after that user has created a forum name and logged onto the forum at least once...
Until a new forum member has been validated, they can only post in a special forum area and then their posts are only seen by mods and admins.
The processes here I'm sure will continue to evolve and improve over time. Today is a small step in the right direction.
