Advertising scams have led to lawsuits plenty of times before, and now social gaming may get its turn in court. The firm Kershaw, Cutter & Ratinoff LLP is “investigating” a possible class-action lawsuit against Facebook, MySpace, and a range of social gaming, offer companies, and advertisers, according to a post on its web site. The firm has a track record in this area.

Here’s one victory, as quoted (its emphasis) from the firm’s web site:

KCR served as lead counsel successfully resolving a class action case on behalf of approximately 11 million AOL subscribers who were double-charged subscription fees through a misleading pop-up advertising scheme

Sounds somewhat familiar. The firm is apparently pretty interested in pushing things forward, as its web page suggests that readers “[r]ead more about this practice” on the Gawker article that broke the news about the lawsuit today.

Here’s the current list of companies that KCR is investigating:

• Zynga
• RockYou
• Offerpal Media
• Super Rewards
• Tatto Media
• Double Ding
• Gambit
• SendMe Mobile
• Video Professor
• Facebook
• MySpace
