Bluesky is a legitimate social network that Jack Dorsey founded, so the platform itself actually exists. Now, about live trivia that promises cash prizes - those are generally real events but they have their catches: the competition is tough, there are tons of participants, and your odds of winning money are pretty slim. If someone asks you to pay to enter or tells you to deposit money first before you can cash out your winnings, that's straight-up fraud. Play if you enjoy it, but don't expect to make easy money.
Live trivia events are usually real, but the catch is in the terms nobody reads: tax withholdings, absurd minimum payout limits, or the money stays as credit inside the app so you can't withdraw it. If you see they're asking for bank details before you can claim your prize or that you have to invite friends to be able to cash out, that's where the scam is. First check in user communities if anyone has actually managed to withdraw real money.
