Meeting someone from an online listing is a choice between adults. A few boring habits reduce risk whether you are in Accra, Lagos or travelling.
Keep early contact on the record you chose
Use the contact method on the profile first. If the conversation immediately moves to a frantic new number and a demand for money, stop.
Meet in public if you meet at all
A public, well-lit place is easier to leave. Tell a friend where you are going. Take your own transport when you can.
You can leave
If the person does not match the listing, or you feel unsafe, leave. No listing is worth ignoring that signal.
