I get the idea of instances, like you can make your own and this is good for privacy. But some lemmy instances are much more popular and this in fact makes it another Reddit. If there are separate instances for niche topics, why not make it another community inside a larger instance?
Yes, but it doesn’t list your communities.
That sounds like an instance just for friends or a family, which is still worse for privacy (compared to a bigger one) in most cases. And probably even rarer than single-user instances.
Your profile contains your post history to many of your communities.
I’m pointing out that if you’re going to the trouble of hosting your own instance you could as well allow some convenient number of random users to register. It would erase most of your signal and help distribute the load and exposure to specific legal compartments.
Allowing randoms to register, would vastly increase your legal responsibility, from both a GDPR perspective, but also from a legal responsibility for content perspective. I don’t think a small privacy win makes that worth it.
That is true, but that is only those you post to, I have many communities I’m subscribed to but never posted to.
> GDPR perspective
GDPR does not apply here. Content that people write on a forum does not count as PII. If you are not sending your users’s IP or email addresses to a third-party, you have nothing to worry about.
Right to be forgotten may well be relevant.
Also applies only to personal information and not to content generated by the users.
