Forbes built a hall of shame for all the questionable people on its 30 Under 30 lists

• Plenty of people on the Forbes 30 Under 30 lists have turned out to be not quite so shiny.
• Forbes compiled a "hall of shame," highlighting some of the names they now regret picking.
• They include Sam Bankman-Fried and Martin Shkreli, among others — and most are in finance.

The Forbes "30 Under 30" lists celebrate the achievements of young people making a mark in a range of sectors. Unfortunately, quite a few of the picks are now a little questionable, to say the least.
