Before you install a Lemmy instance (and I am guilty of promoting them as well) please be aware, that Lemmy's creators are unabashedly pro-China and have a history of censoring anything pro-Democracy, in China or elsewhere, on their own instance.
Lemmy's creator was banned from r/socialism for posting Nazi literature and is an avowed anti-Semite and Tankie: https://raddle.me/f/lobby/96713/heads-up-the-tankie-behind-lemmy-ml-got-banned-from-r
He is also an active climate change denier and believes that Uyghur "reeducation" is necessary.
Lemmy does not delete deleted comments or users: https://raddle.me/f/lobby/155371/warning-lemmy-doesn-t-care-about-your-privacy-everything-is
If you're considering joining a Reddit clone or running one, consider kbin. It's not quite "there" yet, but aside from abiding a bit more by Fediverse standards, it also doesn't benefit an anti-Semitic tankie asshole.
