I just got a call from the constable.
I know who the troll is!
I'm not going to reveal the name here just yet, not until formal charges are filed. However, it was, as I suspected, a former employee at my workplace; I recognized her name (yes, now I know for sure it is a woman ;)). The weird thing is, though, she's not anyone I know really well. In fact, if it's the woman I think it is, I've only ever had one conversation with her. There was a reason for that; I didn't like her much. It would appear that feeling was mutual...
The constable will be talking to her within the next few days. In the meantime, we'll be investigating at my workplace to see if she might've had any "professional" reason to dislike me that might've prompted her to do all this.
Stay tuned!
