The ~7000 QAnon accounts they banned don't fit your narrative I'm afraid.
There are now several intermediate steps they've added since then, like clear warnings [1]. This allows the account to stay active and still report on stolen data. Much better IMO, banning accounts is common practice, but too heavy-handed as to be the only tool Twitter has.
