I’m assuming that you may be referring to this thread:

If that assumption isn’t correct, feel free to post a link to the thread you are referring to.
I wasn’t involved in this action, but Nature Talk seems to be the best place for the type of post which asks about IDing a specific group to me. My reading of the initial post wouldn’t be that it is about a more general issue of
but about a specific genus of grasshoppers. The questions in the initial post refer to Melanoplus several times and the title includes a specific taxon. The final line is
The reviewers replies also address you specific observations.
So in general, these types of posts which are focused on identification tips/approaches for specific taxa are often placed into Nature Talk, either by the initial posters or by moderators afterwards. I think this is generally because they are focused on the taxa (not a feature of iNat per se), and are applicable to IDing off of iNat as well. Here are some examples of similar topics in Nature Talk, including some you posted there (that I don’t think were moved by anyone):

https://forum.inaturalist.org/t/identifying-powdery-mildews/34001
though there are lots more.
That said, I’m sure that there are also some similar posts in General as well depending on when mods were active, how much time they had, etc. I don’t think that there’s anything negative about moving something to “Nature Talk”, and if there are any sorts of issue that are serious or where a response from a poster would be important, a mod would generally reach out personally or leave some sort of comment. I think this type of categorizing is just “general housekeeping” and a pretty normal part of the how the forum works.
