Will manifold introduce a rule or a guideline of some sort against duplication of ongoing markets?
resolved Dec 29

could be suggestions like : a user should only duplicate an ongoing market if so and so conditions hold true

Market is for 2023.

It happened and I've done this to multiple markets. SirSalty said it was a good idea and we will continue doing it.

Not sure if it counts for this market or not but general PSA that we are now unsubsidizing low effort duplicates of popular markets.

Edit: Screenshot didn't show finalized rules so edited out.

predicted NO

@Joshua whoah this is insanely invasive

predicted NO

@Joshua discussion elsewhere

predicted YES

@Ernie Oh, no don't take eliza's messages there as all being the rules now.

predicted YES

@Joshua I don't think anything is being done to existing markets, just new duplicates. Guidelines are being formally updated.

This might be considered a guideline against duplication:

@JimHays it's a display of existing questions, I do agree that it discourages creating duplicate markets. However it's very implicit, and not a rule or guideline of some sort against duplication of ongoing markets (there's a duplicate market button on each market, for example, and Levi abused it by duplicating most of the popular markets)

A merge tool would be an even better option

Multiple markets provide choice for a trader as who they trust more to give a quick, fair and accurate resolution.

Does SirSalty saying I'm not allowed to duplicate a bunch of markets just because I want to count?

@levifinkelstein ofc not. Its a user being warned. Definitely not a rule or guideline for manifold. I'll consider it when it's site wide, not for a specific user

predicted YES

@firstuserhere what if he says nobody else is allowed to do this as well?

@levifinkelstein I'd be inclined to say that if it applies to everyone or almost everyone, it should count, but the beauty is that we can just ask @DavidChee if he means it in the spirit of the market :)

Rules come with enforcement overhead. The real question is does Manifold have the resources to enforce this, especially when the resolution criteria could make them subtlety different markets.
A guideline, is more likely, but with out enforcement, or incentives (positive or negative) I am not sure how effective it would be.
