They’re “investigating”? lol, What are they going to do, subpoena phone company to get transcripts of your private conversations?

As far as you know all that happened is some jerk was making stuff up about other people. Ignore, and deny. Teen boys wank it to literally anything, and nobody wants to know about it anyway.

Truth or dare is a party game, you don’t need to actually tell your secrets, and anything you want to stay secret should NEVER be told to anyone. Ever.
