The more granularity and internationalization the higher likelihood it'll be used for grooming, sex trafficking, and fraud. Tinder, Snapchat, TikTok, and other mediums are already rife with it.

One of the reasons dating sites like Match don't work easily worldwide is because there are too many variables. Local customs, society judging online dating, personal information that may work in one area but not another ("do you attend church on Sunday?", etc).
With the added fact it's essentially live FaceTime, you also get rid of people pretending to be a 17 year old girl when they are really a 40 year old man, or claiming they are are a US military veteran who needs some quick help when they are actually a Nigerian prince.
