The Blotter is reporting on some “edgy” online videos that have sprung up anonymously which trash GOP candidates.

The Daily Background blog noted the ads had been posted to several online forums by a MySpace account which appeared to belong to an employee of the Washington, D.C. political advertising firm Stevens, Reed, Curcio and Potholm. The firm gained prominence in 2004 by producing ads for the group “Swift Boat Veterans for Truth,” attacking Democratic presidential candidate John Kerry for allegedly lying about his war record.

The firm now works for Sen. John McCain’s presidential campaign. Executives there told ABCNews neither the firm nor its employee was involved in creating or disseminating the ads.

“This is a complete fabrication and a hoax,” firm partners Rick Reed, Paul Curcio and Erik Potholm told ABCNews.com in an e-mailed statement. “No one at SRCP was involved in the creation or production of these ads or the personal content created and posted on MySpace which is attributed to one of our employees.”

A campaign spokeswoman for McCain told ABCNews.com neither the candidate nor his team had any knowledge of the videos.
