There's one who comes on every single day (ban evader) and samefags their own thread to bump and feign popularity. They usually post OPs about China outside of the general or another non-leftist news with a link at the bottom, they use reddit spacing and clearly don't know what anti-capitalism is.
I left this thread up since it became popular, but you can see the redtext notes added after their ban. >>>/leftypol/413815
This is their typical writing style. Feel free to add that 'do not reply' poster when you see them.
