Is a dating app match who only messages me late at night and never during daytime a scammer?

Romance scam operations are often run from overseas, where agents manage many 'relationships' simultaneously using scripts. Messaging exclusively in the early hours of your morning can reflect working hours in a different time zone. Other timing patterns include extremely fast responses at all hours — suggesting a script rather than a real person — or sudden long silences followed by effusive catch-up messages. Timing alone is not proof of a scam, but combined with other signs — no video calls, a profile photo that returns results on a reverse image search, or early mentions of financial trouble — it warrants serious caution. If you are suspicious, suggest a spontaneous video call at a time convenient for you. Scammers usually cannot produce an unscripted live video of the person whose photos they are using.
