I use Fediverse Obsever, which, for example, shows instances that allow signups, (ex: registration is disabled for lemmy.one) but am not sure of many instances where you don’t have to type a verification (besides lemmings.world). I think it’s good to have a typed verification, I’m just wondering which ones don’t.
Earlier I used to hate instances that did this, but now I think it’s okay. Its like joining a private community. But hey I only had a single experience with this verification, so don’t know much about it now.
