So, don’t learn to code? If you don’t have any reason to and can’t find any motivation, maybe it’s just not for you.

I think this is not really inline with the philosophy of the main Lemmy devs. For this to happen, I think someone else would have to do the work of creating the random selection service. If it was popular enough, maybe they’d put a link on join-lemmy.org

Easy, just create the equivalent of multireddits.

Can your instance not do that as is? Just spin up a bunch of fake users and make them all vote on something?

That seems high when you extrapolate that to 10000 users, like a larger instance might have.
