Various self-referential markets can be manipulated with Manifold alt accounts, eg "will the number of NO bettors be more than the number of YES bettors?". Markets like this are already subject to de-listing under "Markets only about their own activity". Will Manifold go further and ban such markets?

Resolves YES if alt-manipulable self-referential markets like this are subject to deletion or being admin-resolved to N/A or otherwise banned.

Resolves NO on 2024-04-18 if such markets are still allowed and subject only to de-listing or lesser measures.

I may resolve PROB for an outcome between YES and NO. Please ask for details.

Background: manifold recently updated its community guidelines to further discourage use of alts: https://help.manifold.markets/community-guidelines

This creates a "policing" problem, and alts are hard to police. Manifold employees have better things to be doing. Manifold users have better things to be doing. New users may be falsely suspected of being alts. And allegations of sock-puppetry can be very divisive.

To make matters easier Manifold could ban such markets. This "demand reduction" approach is much easier to police and has other good effects,
