Thank you for this balanced response and correctly identifying 2 main issues.
Regarding 1st issue, may I recommend adding a link to community’s effort to help creators in taking better cover photos? The Ultimate MakerWorld Photography Guide or have that transferred to bambu wiki with appropriate credits.
Also for the 1st issue - since print profiles require “at least one photo of real print” already, may I suggest requiring real photo to be a cover image of a print profile? After all - print profiles must demonstrate printability.
As for 2nd point, I echo @h3li0 concerns. I hope creators will be notified and given appropriate time and venue to defend themselves against false positive identification and you’ll use that to improve the process of identifying misleading and spammy models.
This is a topic for another discussion, but I need to express that this is way too limited - the blocked and preferred categories offer only top-level categories and limited number of them. For example: one cannot block that way hueforges and lithos and not block cool signs from Make My Sign.
