By having a Facebook account, even if you don't use it, you are feeding FB data that they can use against you. Remember this thing runs 24/7...
bad happened with cousin for meeting a guy from fb then my parents force me to stop using & told not to talk to strangers on net. then i found crypto and brian told me about memo.
The main factor proably is because you can not send DMs here, everything you write here is forever public. That prevents a lot of people from asking for phone numbers.
maybe... but i also join telegram because whatsapp is also deleted... and nobody say bad thing there also... crypto people are good and much much more civilized... my conclusion.
