No, infinite ethics is not a serious problem and doesn't deserve criticism.

Yes, infinite ethics is a serious problem and deserves criticism.

I think the wording of your options is a bit misleading. It's valuable to publish your criticism of any topic that's taking up non-trivial EA resources, regardless of its true worth as a topic - otherwise we might be wasting bednets money. The important question is whether or not infinite ethics fits this category (I'm unsure, but my best guess is no right now and maybe yes in a few years). Whether or not something is a "serious problem" or "deserves criticism", at least for me, seems to point to a substantively different claim. More like, "I agree/disagree with the people who think infinite ethics is a valuable research field". That's not the relevant question.

A note on counting: comment karma and upvote number are not really the same thing. Even in the absence of downvotes or strong votes, some people have a small vote power equal to 2.

Im very interested if infinite ethics includes the possibility that a person's sentience can persist for infinite time (i.e. wat lots of religions claim)

I'm not sure what you mean by "it deserves criticism" I think Infinite Ethics is a serious subject, but which we should study in the Long Reflection.

I object to the very existence of this survey
