Getting banned from Lemmy is orders of magnitude easier. During my 10+ years on reddit I can only remember one occasion when I got banned from a sub but it has happened on Lemmy multiple times over the 1.5 years I've been here and comments being removed is a regular thing.
On reddit you need to actually break the rules. On Lemmy it's enough that a mod doesn't like what you're saying.
And the sub doesn’t even have to be related. I got banned from commenting in r/thatsinsane for a comment in r/karma4u, can’t even remember commenting there.
Getting banned doesn’t really have the same impact. In both cases, you can still register with a new email, but on Lemmy, you can also choose a different instance.
