100% agree that they are trolls. They flood any China news posts (that’s not on lemmy.world) with a truckload of pro-China comments, taking advantage of the fact that a sizeable portion of Lemmy users won’t be able to see and downvote them. Whenever someone replies to them with well-thought-out arguments supporting “the western authoritarians,” half of them replies with huge and ugly emojis, while the other half parrots more Chinese propaganda (that actually sound well-written if you disregard the fact that China is an oppressive regime).
