Wow, this is harder to answer than I thought.
Yes to relatively normal, well-taken photos showing the person in a range of activities/places/moods. They are only showing their personality and interests, after all.
No to:
- only group photos
- no photos of the person at all, just items or abstract pics
- 3-5 of the same front camera, looking-down-at-phone photo
- photos that seem outdated, especially if it's of an older man with one child (classic scammer)
- holding a fish
