I'm guessing this is primarily snark, but there are a lot of tweets that are pretty good signal of bad behavior. I'm not talking about some nuanced difference in opinion. For the tweets I'm talking about knocking out everyone that liked it wouldn't be a big deal.

Sure some may use this to craft an echo chamber for themselves, but they're already doing that anyway - and a lot of people 'hate follow' to stir up abuse intentionally to drive traffic. These people wouldn't find this tool valuable because they feed off of the nastiness to drive engagement and grow their audience.
