I have had this happen before a long time ago and nothing came up but this time I did it because I’m stupid and I can’t help myself. I had sent a pic of my face and then went on a Snapchat video call, and then they said that it was blurry and to send another, so I blocked them and tried to forget about it, I hopped back on snap and saw a message from another account with a image being sent to “the fbi” and they said “do you want them to know about your scandal I have all your friends and family and I’m going to send it to them” so I just blocked them again, the Snapchat was a burner account and I had not given them my number or email it was on a dating site, will any harm come to me for blocking them or is this a harmless threat
