At least two firms are encouraging users of AdultFriendFinder.com (and similar services) to contact them, in response to allegations of fraud in the form of phony profiles:

• http://www.audetlaw.com/adultfriendfinder/index.html
• http://www.alexanderlaw.com/adultfriendfinder/index.html

The theory is that fake profiles are created to tempt users to pay for membership suscriptions and upgrades.  Some of the allegations--and rebuttals--can be found at http://www.ripoffreport.com/reports/0/177/RipOff0177561.htm.

If actions are actually filed, will they survive demurrer and class certification obstacles?  One thing is certain: discovery will be very interesting if any cases make it that far...
