I think they’re banned for similar reasons to why Fox News articles are banned. I agree with your comment above - the source doesn’t necessarily make something false. It would be silly for any outlet to post only misinformation. But some sources are worse than others. I wouldn’t read any news about Ukraine from either Ukrainian or Russian state-owned sources. They’re one sided to the extreme.

Regarding alt right - that might be a stretch, yeah. They’re conservative (for example, they’re anti-LGBT because it’s banned by the law) and telling how’re liberating Ukrainian people. But I don’t think it’s qualified as alt-right.

I provided one of the examples: https://lemmy.ml/post/44675222/24621308
