I'm on lemmy.sdf.org because it's widely federated and run by a trustworthy organization.
I'm not much of a tech bro - in fact I struggle with troubleshooting basic Linux issues. That's why I mostly interact outside of my local instance.
I hardly engage with the techy discussion on SDF, but I appreciate the high quality user base.
I read through the user profile to decide whether or not to block them. Don't bother with voting from their profile.
