Creality Cloud just started doing something like this. It’s not as involved as what you suggest. You just get 10 points for uploading a photo comment on up to 5 models per day, provided you have downloaded those models.
I’m not trying to rain on your parade, but any new way to make points must be evaluated on how open it is to exploitation. You have to also consider how much extra work it might create for MW employees. Rules will be put in place, and people will break them. Reports will be filed, and then someone will have to deal with that.
This whole scheme of outsourced pictures might help people/user/browsers, but I dont think it has any place in rules or moderation. I really dont think you should offload the responsibility of photographing real prints of models away from the real uploader. Every party can then point to each other as being “in the wrong.” Systems designed like this thrash themselves to death
While I like the principle, it should be the designer supplying their evidence of their design successfully printing in their printer.
If they don’t, they are not playing their part.
I am aware this is not the sole reason for the suggestion, but it will have an unforeseen side effect.
The photos from users have value, I especially like seeing their colour choices. Should this feature move forward they should be presented as a distinct feature rather than blended with the designer’s own photos.
