I’m pretty new here too, but from what I understand you’d need to create a new account if you want to log in to Lemmy.dbzer0.com - however, you can subscribe to communities on other instances from your Lemmy.ml account. Search for the other community by typing it in the search bar like this; !communityname@lemmy.dbzer0.com and then you can subscribe.
Or in the address bar, like this: https://lemmy.ml/c/div0@lemmy.dbzer0.com
You can also go to https://lemmyverse.net/communities, set your home instance to lemmy.ml (or whichever you want), and it’ll automatically link you to the correct place to see it on your home instance.
There’s also https://addons.mozilla.org/en-US/firefox/addon/lemmy-instance-assistant/
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn’t work well for people on different instances. Try fixing it like this: !div0@lemmy.dbzer0.com
Feature request: per-user opt-out. I know how to link properly and when I don’t it’s intentional.
Sorry for the late reply, I don’t read answers to the bot very often. You can block the bot and it won’t see your comments/posts anymore and thus it can’t respond.
I just search for them on my home instance, subscribe, and then comment/vote from my home instance. No reason to sign up everywhere.
