I agree with the need for improvements in the puzzles. I have often wondered about the themes suggested. I have pressed the "thumbs down" hundreds of times. I can't believe anyone actually took the time to spam the passed pawn theme. I think it's more likely that some form of computer analysis is to blame. But whatever the culprit, it makes using the themes a waste of time.
I have wondered who monitors reported puzzles. I haven't figured that out yet.
I'd have to say that 9 out 10 puzzle "bugs" reported here were actually not bugs, so I understand why they don't answer every query.
Meanwhile, I'd suggest sending your post via email to support@chess.com. The staff diligently tries to find the right contacts for suggestions.
See this discussion (https://www.chess.com/forum/view/general/suggest-theme-in-puzzles-needs-moderating), reporting here as well as I believe it’s a bug in the system and it’s greatly deteriorating the “puzzle experience”. While I have little hope this’ll get any attention from @chess.com team (I’ve seen many other unanswered reports, unfortunately), ‘not reporting’ at all would be even worse.
Bottom line: some themes, like ‘rooks on 7th’, ‘passed pawns’ and others have been selected for many puzzles, the passed pawns theme for almost every puzzle (!!). Since the tiny thumb down/up buttons have no effect (I’ve yet to see ‘passed pawns disappear from a mate in 1 without any pawns on the board, and it’s been over a year), this is clearly flawed and makes using puzzles in ‘custom mode’ virtually useless as a premium (paid!) feature.
Puzzles are great and add value, but they require maintenance. Same is true for wrong puzzles, what use is the report button if no action is taken, or it’s not possible to follow up (something like ‘thanks, we looked into it but didn’t see a problem with the puzzle’ is better than no feedback at all, which is the current modus operandi).
While you’re at it, the ‘suggest new theme’ stopped working as well (I’ve selected it on blank puzzles that were a clear mate in 1 or 2 and checked back later to find that it wasn’t added, which makes this much like a Sisyphus action).
Please, chess.com, join this discussion and talk with the community to improve this otherwise awesome feature of this site.
