jointhefediverse.net seems to be a commonly linked resource for directing people to join the Fediverse.
Curiously, it does not list Lemmy under the list of Reddit alternatives. Their GitHub README explains why.

I agree 100% with this. The developers or the operators of lemmy.ml may be assholes, but the beauty of decentralization is I can simply not use their instance. I do not. Thus, while a warning label is necessary, I think more good is done by making people aware of the alternative to Reddit than by sweeping the whole thing under the rug.
As for user privacy, I’m not sure Lemmy is any worse than any other Fediverse app. There were a couple of bad things like being unable to delete a hosted image, but that has been fixed. Once again, warning label, not rug sweep.
