Going by comments in the post, the required login is coming in waves, so not all people may notice immediately.
Still, as Reddit is strong-arming its way across, maybe worth signaling to people there that the fediverse may be used without an account, so long as there’s even one instance that implements logged-out view as the protocol allows it?
I don’t have access to my account any longer, possibly VPN ban, though I never tried to recover it so I can only guess why mine is lost, else I’d post myself.
If Reddit account is still available and you’ve got the time & energy to convince some people to switch - go for it. Make sure to not enrich Reddit with anything else. I’ve decided against this way, because I wasn’t sure if I’m still talking to real people and the possibilities of spreading the word are very limited (posts often get deleted by mods).
Feels much better to feed the fediverse with content in my opinion.
