Here is the secret: most leftists don't like tankies. Ban them as well I say! I people want to defend Stalin's murderous regime then I don't want them there either. Appealing to some hypocrisy here isn't super useful since the large bulk of people who don't want fascists on their webforums also don't want tankies.
It's also so vague, it's useless. There's "tonnes of <literally any type of person>" on Twitter. No presented evidence/claims that the number of them (relative to anyone else you don't like/don't agree with) is causing an issue, or that Twitter has a structural problem that raises the voices of tankies.
