We don't need props... It's just a little something آپ get for doing whatever it was that made آپ deserve it. I guess it's just there to دکھائیں what you've done that made people happy یا what your شائقین gave آپ just to be nice.
People give سہارا to others to دکھائیں emotion and دکھانا that person cares for something awesome آپ did, یا it's also because people like users icons.
