In nearly every season of The Circle, the social media competition series where popularity is king, there’s a moment like this: The contestants grow wary of a catfish, reading through the lines of their vague comments. They ask the suspected catfish a question, something only the real person in their photographs would know. For Season 2’s DeLeesa, catfishing as her husband Trevor, it’s identifying three famous basketball players; for Season 4’s Alex, posing as frat boy Nathan, it’s golf terminology. The catfish is sweating, frantically tearing through pages of notes, before they realize: They have to guess and risk their entire game.

For some of these players, the risk pays off: After a correct guess of Scottie Pippen, DeLeesa takes home the Season 2 crown. But for others, the wrong move can lose them $100K (and cause one slightly embarrassing television moment). Here’s your guide to all the ways contestants have correctly caught Circle catfish, from sussing out the filtered fakes to going full boy band stan.

Go #NoFilter.

All the way back in Season 1, Karyn commits one of the first catfish cardinal sins: using the Valencia filter a few too many times on a picture of her alter ego, Mercedeze. Sammie is immediately put off by this, and Antonio waters this seed of doubt by dropping a hint in his goodbye video. During an Episode 5 game, nearly everyone accuses Karyn of being a catfish, and she’s eliminated in the next episode.

Study at Sephora.

A few players already had doubts about Emily, played by college kid Jack in Season 2. But when Queer Eye’s Jonathan Van Ness comes around to give the players a makeup challenge, Jack can’t do a smoky eye to save his life. Later, Mitchell asks him what his top five makeup brands are, and Jack responds with the made-up “Collection Co.,” sending Chloe into hysterics and all but guaranteeing his blocking. Sorry, Jack: The beauty guru life isn’t for everyone.

Consult a Circle dictionary.

Parker, playing her 56-year-old father, Paul, in Season 4, makes her first mistake when she reveals she doesn’t know what a memoir is (“a story of your life,” Alyssa helpfully supplies). Bru, Frank and John/Carol all immediately clock the error, and, after a few more dicey moments in games, Parker becomes the first Season 4 player blocked from The Circle. At least it’s a great moment for her future memoir.

While pretending to be his 63-year-old Italian mother, John encounters a challenge that would even be hard for Nonna. In Season 4, Episode 2, players are challenged to a cake-decorating contest, which, needless to say, isn’t John’s bread and butter (or, in his case, tiramisu). The other contestants have their suspicions, which are only magnified once Parker drops a coded hint in her goodbye video. By the time John is eliminated in Episode 11, pretty much everyone has called him out as a catfish.

Go full stan account.

Lisa, Lance Bass’ personal assistant, is certainly well prepared for the challenge of playing an early-aughts pop star, but even she falls victim to catfish paranoia. Seeing an *NSYNC boy bander in The Circle is already pretty suspicious to the group, but when Khat arrives and sets a trivia trap, Lisa takes a bite of the bait when she fails to answer Khat’s question about an extra-special costume. That’s certainly one way to make a catfish go “Bye Bye Bye.”

Hope they just... tell you themselves.

In case you forget: This really did happen (and was definitely more heartwarming than you imagine). After using a friend’s photographs upon arrival, Season 1’s Sean updates her profile with her own pics to show the group her true body type. It’s definitely the easiest (and most effective) way to catch a catfish.
