"Free API is being abused badly right now by bot scammers & opinion manipulators. There’s no verification process or cost, so easy to spin up 100k bots to do bad things."
This announcement and today's ban-wave that followed seemed like someone not accustomed to Twitter just knew there are bots, and thought it to be workable idea to sample global timeline and script ban duplicates, which of course is not workable at all and only maximize harm on real users.
If I looked hard enough I could probably buy 10000 verified twitter accounts with API access right now, aged 1 year or older.
I would think mobile carriers keep that in their own house
