"M" is someone I met online. We communicated primarily via Telegram. It developed and escalated over time, and (to my chagrin) we made plans to meet in person, in the place where she is alleged to live. Some of the escalation involved Internet-based or -enabled conversations and video, and some of that is intimate (or, depending on how you look at it, pornographic). Anyway, it would obviously be embarrassing if not catastrophic to my career.
I was supposed to visit her departing 9 November and returning 12. The morning of 9th she asked me for $1000 in support of the visit, including money to pay her roommate (I'll call her "B") to be sent as bitcoin. I sent this (it is not part of the "loss" report). It was the last communication I had before I was supposed to set out. I asked, more than once, for some additional information, but the communication had apparently gone dark. I chalked it up to experience and figured it was as well I didn't drive all the way to her. Some while later I heard from the supposed B via M's Telegram account saying M had been arrested. The coincidence seemed pretty weird, so I attempted to shut down various avenues of communication, but it was apparently too late.
Someone claiming to be M contacted me via Twitter (on a public thread, not a DM, but the comment was to me. It appears it has since been deleted and I didn't have the presence of mind to dig deeper at the time). Anyway, the threats of the "exposure" are what you'd expect: I send money or videos get posted. I am not convinced it is the same person: conversations involving details previously discussed seem to miss some of those details. It's like the original M has been replaced.
