maybe not in all cases but sometimes people use multi tags because they have no idea there is any netiquette.
I would use both #vyb and #proofofbrain in a generic post.
would probably add some more as it is frustrating that nobody comments, even if I try to write the best content I can in my limited time.
If I break some rules I am not aware of, I would be more than happy to be informed about it in the comments first. If I do it again, then I think people should be ignored / muted.
Best regards!
