Of course you got instances like:

lemm.ee lemmy.ml lemmy.sdf

lemmygrad.ml hexbear.net

beehaw.org lemmy.blahaj.zone

programming.dev

But really, whatever instance you choose

Just for comprehension

If everyone here in the comment section chose lemmy.ml in their comments, as part of it, then lemmy.ml approval rate is 100%

If half of everyone chose lemmy.ml in their comments, then lemmy.ml approval rate is 50%

But there is more than one option, at least

But if you want to show your opposition to other instances, just don't mention them at all...
