Is it legitimate on Manifold to make comments intended to push the market in (what you believe is) the wrong way?

E.g. if you want others to bet YES so you can then bet NO at the higher price, or sell out your existing YES shares.

Option 1 means that this is always considered bad behavior - your comments should only ever be intended to make the market more accurate. (Of course, you can and should bet before you comment!)

Option 2 means it's OK as long as your comment does actually provide value to traders on the market, regardless of your motive. E.g. you share news that does legitimately raise the YES probability. You expect others to weigh it more strongly than it deserves (in your opinion), but you don't actively slant things to cause that; it will just be their own reasonable opinion. Or you make an argument that you believe a smart reasonable person might sincerely make, with phrasing like "a point in favor of YES is..." that doesn't imply you agree.

Option 3 allows more: presenting selected partial information that gives a distorted picture, arguing with feigned sincerity (but using true facts), and all the other ways of misleading-without-lying.

Option 4 is that Manifold is just an adversarial game environment like Diplomacy; say whatever you can get away with.
