When someone sends you a SuperCrush, it shows up in your “Messages” in the SuperCrush section that is on top of all the messages. If you'd like to accept this SuperCrush, you only need to tap on it to access the profile and then click on "Accept". However, if you do not want to cross paths with that person again, you can tap on "Refuse". You can also do both actions by clicking on the three dots next to the SuperCrush. To accept the SuperCrush, you can click on the check mark, to refuse, you can click on the "x".
