Of course, why not?
Lemmy is pretty much like reddit in this regard
Well, no. Unless you take serious precautions (like using vpn and a different browser) for multiple accounts, reddit can easily track and ban ALL your accounts, effectivly locking you out of reddit completly.
This is not possbile on lemmy where you can simply make an account on another instance.
Now that’s a different question. OP asked if he can get banned. You are talking about what after being banned.
(I have used several reddit acc’s simply with different apps, even at the same time, and never had any trouble after one of them got banned)
With the difference that there’s multiple Reddits; each with their own set of admins.
Yeah, but you can only get banned from an inatance. You can always migrate to another instance (another url hosting lemmy)
