The real "no fly" captains are some of the 2014-2016 hires, who suck as a captain.
If you spend 95% of your time playing online games while flying using your friends T-Mobile (You are here, you suck and everyone hates you btw), you shouldn't be on the left seat.
The Captains on the famous "list" aren't that bad. The FOs who wrote that list are now the CAs who should be on it. There's only a couple of senior guys who are a**holes.
99.9% of the pilot group is solid.
