 is able to guess which response to their Manifold survey was submitted by me. Otherwise, it resolves as 

 upon them making an incorrect guess or on October 21, 2023, whichever comes first.

I think my responses were pretty obviously me, but I also never explicitly stated my username in any of the free response boxes or anything like that. 

 can guess by taking a screenshot of one of the responses to their survey, posting it in the comments, and saying "This you?" or something similar. I suspect that some of my free response questions might obviously be from me, and some of the other questions might help narrow it down (anyone who's seen me be active on this site since May knows that I think Tears of the Kingdom is an excellent game, for example.)

Since Plasma won't be looking at any survey responses before October 7th, that's the soonest this market could resolve.

I am not posting this question immediately before or after submitting a survey response; there is no temporal correlation to rely on. Maybe I submitted a response yesterday, maybe I'll do it in a week.

 outright refuses to guess for any reason, then this market resolves as NO early.
