Most people here are exactly who they say they are. A few are not, and they tend to behave in the same recognisable ways.
Signs worth pausing on: they want to move to WhatsApp or email almost immediately. Money comes up — an emergency, a fee, an investment, a transfer they need help with. Their story about their congregation or circuit doesn't quite hold together. They avoid a video call, always for a new reason.
Never send money to someone you met here. Not for a flight, a visa, a hospital bill or a business. If it has come up, report the conversation — you won't be the first.
