As @JosephMenn reports, Russian propagandists are eager buyers of Twitter Blue.
This is because Twitter Blue privileges their posts in Twitter's relevancy algorithm, ensuring their propaganda achieves more reach.
It also gives them a fancy blue badge.
Russian propagandists aren't the only bad hombres buying Twitter Blue. A few months ago, I discovered that the Taliban are also paying for the service.
Twitter Blue: loved by Putin and the Taliban!

@rastinza @JosephMenn Your question answers itself.
Twitter can decide who it accepts money from.
Nope, won't be entertaining your sea lioning any more 🙂
