I believe this thing you think is trivial is actually absolutely impossible. Even if Twitter voluntarily gave us programmatic access to their stats and a way to query them (which they probably don't, even if we pay the elon price) then how would we get the data for accounts that were already banned? These would not be available.

In any case I think automating the first step is also not very good, if you're going to approach someone with a crazy idea it's probably better if you know them at least a little bit instead of just having taken their name from a list.
