The change that should be made is to require affirmative action on the users part to insert the showcase. To just automatically assume the users' preferences and insert it just from the issuance of a token is not right.
Most people think it can do no harm, but it can as in my case. I sell primarily coins. Most coin buyers will not buy coins from a seller that primarily sells other things and all of a sudden has a coin or 2. Their reasoning being that the seller knows nothing about coins.
When you automatically put those things in my listings, all that showed up were bolo ties that happened to be running, it gives the impression that I don't normally sell coins and could hurt my sales.
And I didn't ask for it, you just did it.
