I probably wouldn't classify it that way. It's a cesspool but not really what I'd consider "far right" like say Stormfront.
You'll find people openly arguing with Nazis so it's not really fair to say it's a far right forum as much as it is just a complete cesspool where the worst side of people comes out.
FWIW I wouldn't really consider Telegram a far right forum either even though they're definitely there and highly visible.
