Hexbear suffers from the nazi bar problem, they’re not ALL tankies, but they sure do hang out with a lot of them
I just don’t have the time to sus out who’s who and it’s much easier (and less massive-shock-image-spamming) to use an instance that’s defederated with them
Every single one of your upvotes on lemmy is already public due to how the protocol works, it’s just currently obscured by a bit of work to get them (have to run your own instance, assuming there already isn’t some online tool to easily look them up)
Making them publicly and easily visible would only remove the illusion of privacy we currently have, not actually make your upvote logs less secured in any way
