Hello. I use my personal account on Facebook and have most of used inventory listed for sale. I talk to many many people on there without phone numbers as they can call/msg/video from messenger app so there is no reason they need a phone number. In the FB Marketplace there are tons of spam, and asking for a phone number usually ends up in a person blocking or reporting you. Bc there is literally no reason to ask for a phone number- you are already communicating via msg. I can not record communication in calls or texts so even though I am - so it looks as though I am not doing much calls/texts regarding management / communication logs. I get a phone number and personal information when they show up for an in person appointment.
