If there truly is no broker, you can always offer to submit a written affidavit under the penalty to perjury that you did not use a broker. Given that perjuring yourself can make you wind up in jail, make sure you understand what AA means as a broker (e.g., in the affidavit or otherwise). For instance, could a section on a web site constitute a broker? I don't know.

Lastly, this info should not be construed as legal advise. Check with your personal lawyer to determine whether this is an advisable course of action or whether a different course would be more prudent.
