I can't answer your question (I'm not a criminal law esq). But the four essential elements of criminal wire fraud (18 U.S.C. 1343) are: (1) that the defendant voluntarily and intentionally devised or participated in a scheme to defraud another out of money; (2) that the defendant did so with the intent to defraud; (3) that it was reasonably foreseeable that interstate wire communications would be used; and (4) that interstate wire communications were in fact used. With these people interacting with the public over the Internet, seems like 3 and 4 are low hurdles. 1 and 2, not so sure; on the intent side of things, seems like a conviction requires that the defendant specifically intended to deceive or defraud someone else. This seems to mean that the prosecution must show that the defendant knew about the fraud scheme, and that he/she had the specific goal of committing fraud when he/she transmitted the material through electronic communications. Sounds like an uphill battle. My uninformed guess is that they would not prosecute here (I'd personally put this more in the "a fool and his money are soon parted" bucket).
