There are have been many moments when Silverboy and Taffy have provided useful information and made interesting, thoughtful and opinionated contributions to this forum.

Can you please give specific instances of this?

They were a blight on the board. The only valuable contribution they might have given was to be careful. But they did this without any nuance.

The doctor painted all for-profit schools with an evil brush.

Can't think of anything the SB contributed of value. Besides entertainment.
