I think this shouldn’t be one of the first features we roll out for improving safety. As discussed in other threads like How many profile photos should users be allowed to upload? and Profiles for users, there are good reasons for being able to put up more photos, including them being important for communicating across language barriers.
I think if you’re suspicious of people with multiple photos, then that’s up to each individual whether or not they interact with that person. If we’re trying to stop people from choosing people based on physical appearance/attraction, wouldn’t this restriction put the onus once again on the people receiving unwanted attention rather than the perpetrators? Maybe I don’t understand your argument fully for how restricting numbers of photos can improve safety, so it’d be good if you can re-explain it.
Because of how much it would limit usability for people who are using the service correctly, I think it’s something we should revisit if it seems like a good next step after we’ve implemented the other safety features. Perhaps, for now, we can just state that ‘One photo is a good amount’ when creating a profile, but they’re free to upload more.
