In general communism is legal in Poland, as long as you don’t openly promote totalitarian practices (i. e. Praising Stalin and other similar figures can get you in trouble). As far as I know there are a few active Polish leftist Youtubers. Although most of them have very few subs even by Polish YouTube standard, this channels seem to experience growth right now:
Towarzysz michał: youtube.com
He is a Polish Stalinist who lives in France (he had leave Poland due to legal reasons outlined above). His channel was probably the first relatively popular and active polish M-L channel, which had opened the way for other, less popular channels with similar content. I do not agree with everything he says (especially his social stance on things like LGBT rights, where it seems that he tries to pander to social conservatives and reactionaries) and I am not a fan of totalitarian communism personally; nevertheless he made some great content, producing hundreds of videos on topics related to Marxist theory, history of communist movements and states, and current events. This is probably the biggest Polish-speaking M-L channel. Other M-L channels include:
Antykapitalista: youtube.com
Polski socjalista: youtube.com
POSTEPtv: youtube.com
This list is definitely not exhaustive, as there are many smaller channels which you can find by looking at the list of related channels.
As for the anarchist channels, I know this one:
Posłuchaj o anarchiźmie: youtube.com
It’s a very good channel with top quality content. However, since this guy focuses more on quality rather on quantity, he uploads videos rarely (once per few months, as opposed to towarzysz michał, who makes new content daily). Other smaller anarchist channels include:
Radykalny Kinematograf: youtube.com
Antifa TV: youtube.com
Again there are probably few other anarchist channels that I do not know of.
