I saw no such influx but then again I was only into chili growing, general gardening, photography and that kind of stuff.
I'd like to discuss mental health issues as well but personally I don't feel like posting to ADHD or anything when my family or my boss or my future boss can trivially easy (two clicks, no mental gymnastics) go from my post there to my professional profile.
Besides, the term "far-right" is so utterly abused now that it doesn't mean anything except "people I don't like".
