@eusanderse While asking if anyone has certain content is not a direct request to upload that content, I would advise against asking this question because it can open the door to a user offering to upload the content, which again would cause potential for problems for someone should they follow up on the offer.
So I would definitely point out to the user to be careful as their post borderlines dangerously close to a request. If you're not comfortable with that, I'm also fine with being tagged in it so that I can say something to steer the conversation back into a rule friendly direction.
Simply put, asking if anyone has certain content is not directly a request for upload, but it is request adjacent, so it's generally a good idea to avoid asking if anyone has something, but it is perfectly acceptable to ask if anyone knows where that content can be found. One is request adjacent, while the other is more comparable to asking someone for directions to a particular destination or landmark.
