You can still sign up for reddit without a email, but they hide the option to do so.

There is a community here (won't say the name to avoid brigading) where people moved from Reddit after their sub got banned.

The topic? Discussing about an influencer's lifestyle.

Not really the most tech-aware crowd, still they were able to get through this. It's been almost a year now I think, and they are still using their community on Lemmy. Just to show that the entry barrier is not that high.

they didn’t even require an email

That's a good point, curious how they handled the bots and fake accounts over time. Maybe we could have email requirement removed once we have enough tools to detect those.
