From what I have seen over the last 2-3 years, Twitter being a tad... idiosyncratic... in their enforcement of their Ts & Cs is nothing new.
The USA's biggest stochastic terrorist hasn't been suspended despite meriting such a sanction several times over, and I've seen enough instances of the complaints system being abused to silence people (the biggest exponents of "fratting" being pro-Trump/Russia/Assad accounts/botnets and the FBPE hashtag cargo cult).
