Mike can do whatever he wants, he owns the stock. Some may feel using an internet website to advertise product he isn't selling online to be a contradiction of terms but it's a free country. I personally abhor those who A) scarf up plugs with resale their only intent and B) those who buy said plugs with no intent to fish them.
Plugs are meant to be fished, cars driven, good scotch imbibed, etc.
Just my .02 cents
