baloney!!!! education is the answer. you are not going to stop anything by with holding information. As I said before the best defence is a good offence. Its better to help someone "NOT LOSE THEIR SHIRT " than try prevent a suspected forger at getting better. If you truly believe that "fake tags " are that wide spread , and that this is your "true" calling then should you do everything in your power to educate everyone you can so they may determine for them selves if its real or fake.
It seams as though some of you forgot that this a hobby/ business and you forgotten about the hobby side,"helping each other ". What good is it to have all the info and not share it with anyone. Others have helped you by volunteering their info (fender tags, broadcast sheets , and other info) for you to build your data base. Imagine if they were to take the same approach as you are, where would you be then? help the guy out he's obouvisly trying not to be swindled.
