Catfishing is defined as “luring (someone) into a relationship by means of a fictional online persona”. The goal of building this relationship could be any one of the following:

• To bully or harass or physically harm the victim (see: cyberbullying, grooming)
• To gain personal information about the victim to commit fraud with their information

The following may be signs that you are being catfished by a person:

• they have no (or very few) “Friends” or “Followers”
• their profile seems very new / has very little history in comparison to their age
• they avoid meetings & video calls
• their picture is too good to be true
• they claim you’re neighbours / friends-of-friends / related / at the same school/club
• they get serious, over-friendly or intimate way too fast
• they ask for personal information or anything that makes you feel uncomfortable
• they always seem to need help
• their stories seem far-fetched or too vague
