designing a vote weighting system that favors similar instances

Would make the whole thing even worse, as I could create several new instances with 10 bot users each, then hammer out the votes.

The entire problem is that you can’t trace back each vote to a genuine user. It would be bad in case of fake instances that create 100 user accounts and upvote/downvote stuff, but you can ban the instance. It would be a disaster if a big instance creates fake votes (like lemmy.world suddenly adds 1000 fake users and uses them to manipulate other instances, if votes were anonymous you couldn’t check if it’s genuine lemmy.world users or fake accounts).

It would be damn easy to look up the instance and their “users” and see that the users are not genuine. Then ban the whole instance.

The problem isn’t keeping votes anonymous, that’s easy. The problem is bots/spam. You could just create a new instance and then upvote a post from another instance a thousand times. If the votes are anonymous for the other instance it’s tough to say if they are genuine users or just bots.

That’s the main issue here, when votes are anonymous you could easily just spam votes with no way to trace it back. If it’s a rogue instance then fine, you can ban the whole instance. But imagine if lemmy.world starts using fake votes in the background towards other instances.

Be sure to unplug the windows drive before installing Mint to the other drive.

Why would you do that? Totally unnecessary. When Windows is already installed any Linux installation respects it without issues. The problem is the other way around, if you install Linux first and then install Windows afterwards on a second partition/drive it nukes your Linux bootloader.

Especially in times of M.2 drives (which are often behind the GPU) you only annoy people by telling them to unplug their Windows drive first. And they might want to use a second partition on that drive if it’s bigger.
