One of the lesser known players in SpongeTech -- the New York company under investigation by the Securities and Exchange Commission for possible securities violations -- is now floating to the surface.
George Speranza, who sources say was one of the parties who helped create the list of unverifiable customer addresses that SpongeTech sent The Post last month, is also raising questions.
Other than a Web site Nohypenobull.com that touts SpongeTech's stock, Speranza appears to have no relationship to the sponge maker. He runs a series of Web sites promising to sell interested parties pieces of the Brooklyn Bridge and old Yankees Stadium.
But several people recently told The Post that Speranza was calling around to set up virtual offices for some of SpongeTech's largest customers, including Dubai Export Import Co. Ultimately, no offices were set up although the addresses were used in a list of customer contacts provided to The Post by Lippert/Heilshorn, the firm's outside investor- relations agency.
Meanwhile, a woman who answered the line for one of Sponge Tech's customers on the list gave her address as being in Bay Ridge, Brooklyn, even though the company in question, SA Trading, is supposedly lo cated in Miami.
Not surprisingly, the same Brooklyn address is found in registration records for Speranza's Web sites, including Ownapieceofthebrooklyn bridge.com.
Neither Speranza nor SpongeTech returned requests for comment.
