That is some real BS gerrymandering on the part of Twitter.
Accounts that are not "monetizable daily active users" who spam and harass users on the service don't count?
Of course they count.
Just generate random numbers from 1 to 2^64 and use the "/users/show" API by user_id until you've got 100 successful hits that match a valid user, then once you have 100, score the users.
Do you get fewer than 5 out of 100 spam bots? That should be the test.
