I think all instances should block the tankies treat them the same as you would alt right because really there no different they both support facist ideologies
In post WW2 Poland (as late as 1950 I think) there were around 200 work camps, organized by the new 'Communist' government, and some organized by the red army or/and NKVD. At least around 75 thousand people have died in them, most of them Germans, but a non marginal amount of them were Ukrainians, Poles and Lemkos. Not the same scale as the holocaust, no death camps, but it did happen.
