AB's best bet would be to delete his twitter account altogether and remove himself from the bane that is Twitter.
Watched a really interesting Joe Rogan podcast with social psychologist Jonathan Haidt as his guest. It's two hours long but worth it, especially if you have kids that are starting to use technology devices. Haidt talked about how pre-teen, teen and college kids depression and suicide numbers spiked with the advent of the iPhone and social media. If you have kids that are pre-teen, teen or entering college I urge you to watch this podcast (
Link). It talks about kids and how we have F'd them up the last generation.
I believe AB falls into this category.
