Four in ten singles find 'thirst traps' off-putting unless they follow certain rules. A poll of 1,000 dating app users found some red flags related to 'thirst traps', which are photos meant to attract attention.

The top turn-offs include blurry photos, heavy editing, and profiles that don't show someone's face clearly.

Most users think the best profile pictures show personality, not just looks. Grindr says personality is as important as appearance.

To prove this, Grindr worked with Keegan Hirst, a former rugby player and model, who helped festivalgoers take better photos.

Keegan Hirst shared the rules for good 'thirst trap' photos.

Hirst said 'thirst traps' are about confidence, but the best ones don't try too hard and show personality and attitude.

Hirst also said that updating profile pictures can boost confidence and lead to more conversations.

Users like candid, spontaneous-looking photos and well-lit images. They also prefer people who don't take themselves too seriously.

Hirst hosted a selfie workshop to help festivalgoers improve their photos.

A survey found that most users are more likely to talk to someone with a 'thirst trap' in their photos. A good photo gives off a fun, confident energy.

The best places to take 'thirst traps' are in front of bedroom mirrors or in gym locker rooms. Many users re-take their photos after seeing someone else's.

A spokesperson for Grindr said the app is a place for users to express themselves authentically.

For the Grindr community, a photo is not just a picture, but a statement of confidence and a way to connect with others.

Grindr is giving users a way to refresh their profiles and show off what makes them unique and attractive.
