Just memes are acceptable
The challenger already lost all 4 cases (343, 344, 355, 356) against my memes and tries to change the policy to condition diffusion by challenging again.
There is no different interpretation than what the policy lists as a possibility: "Are memes related to Kleros or its dapps. Accept: A juror meme."
Memes in the Kleros collection are still good because they can be used by anyone and impactful. Some people get their onetime posts liked by the same 5 friends all the time, but is it much more useful?
The sharing across social channels or number of views are another possibility, separate from being a meme. It shows an example of a meme liked by 5 but it's just an example. The last possibility on the first page is being just a meme and the example doesn't have likes. A meme both with likes or no likes is acceptable.
