1 year agoA lot of those subs went private now so they might’ve gotten knocked off anyway. My guess is the algorithm doesn’t favour private subreddits. Not saying that it couldn’t have been removed deliberately either, but this might be the simple explanation.
I’m not sure if this is different on other Lemmy instances, but on Lemmy.ca I just need to click on “Communities” at the top, which brings up a list of all the communities. Then I can click either Local (Default) or All, which will bring up the community list for just my host or all Lemmy instances. I can also search as well for communities within that page.
