^Because this is shady dealings, like many things Planty does and you shouldn't get yourself involved with such behavior. Its not illegal, but its not "safe" and in some respects, morally questionable.

No offence Planty, but you've got a rep for a reason and this is not one of them. You need to supply an official "proof" to be able to do this to stop naysayers like me when you take this to the convention as you DON'T represent a official rep of those companies.

Otherwise, you also risk getting called up on that from the convention runners. Even if there is no clause for an alarm, better safe then sorry, people have gotten into trouble over less at them.
