Just be careful when dealing with people on FB Marketplace. When selling there are trolls who are only after your information so they can hack your account. Don’t give them your phone number or email. There is no need to communicate outside of FB Messenger. I find the scammers are very quick to respond and quickly come up with a reason they need your phone number or email.
Buying is only dangerous if you try to have something shipped and you pay an unprotected app like Zelle. I will only deal in person with cash buying or selling.
