The online dating world has been set ablaze by location-aware mobile dating app Tinder. However, not all profiles are real people; some are malicious bots. How do you know if the photo you swiped right on is of a legitimate person looking for love or a scammer in disguise? There are a few telltale signs that the person you’ve matched with might not be who they say they are.

The Tinder bots you encounter are just that: bots. They are not real people. A big tip-off is that as soon as you are matched with a bot, they will message you, probably within microseconds. Is it possible that this is a real person who wants to chat with you? Maybe, but it is more likely that the bot was triggered by the match and sent their first message to hook you up as soon as possible.

While this sign is not conclusive, it is the first clue that something is wrong. As you continue to chat, you will get responses back almost immediately, as they are scripted and triggered by your responses.

Unless the Tinder bot is using some sort of sophisticated chatterbot-based conversation engine, it will likely only have a few canned responses that it will give in response to your interactions. Once it’s got a few flirtatious small talk lines out of the way, it will deliver its payload, usually asking you to visit a link that will require you to download something (probably malware) or hand over your credit card information.
