Vip status probably

The check mark means you’re verified (ie the admin has confirmed that a picture of you is in fact of you), the different colors of the check mark are based on the settings: gray means they are verified but can’t see the picture, hollow green means some people can see the picture and you are one of them and the full green means anyone can see them

The heart, star and VIP box are all tags you can choose if you pay for VIP
You can also choose to have nothing indicating you have VIP

means im awesome 🕺

If you decide to verify your account by sending in a photo of yourself, holding a sign with the date, you earn a check mark. That way, SW users know that you are real.

If you buy VIP service, or if someone else buys it for you, you can choose a heart or a star or no symbol at all next to your name.

heart and star means they have VIP. Checkmark means they're verified.
