I mean, this woman is crazy. Clearly. But I'm not sure i would call the police. Seems a bit much. But, if it makes you more comfortable, you should!
Filing a police report or complaint isn't really about getting them to do anything at this point. It's more about making sure that in the unlikely event that this esclates and the woman does something to harm trudge it is documented that there is already a history of harrassment. If she does not stop, a police report now will make it easier to file a restraining order or even press charges later.
I understand all that. Like I said, if it makes her feel more comfortable, she should. I just said that I, personally, think its a bit much.
The reason I suggested the police is because this is the very definition of harassment and it can escalate. It would be nice if it dies down, but this woman doesn't seem inclined to let it go and it would be nice to know what her options are.
Oooo, please please send a copy of all of this to Regretsy! This is the sort of thing she revels in. Also, anyone that's followed Regretsy for any length of time can tell you that Etsy is run by a bunch of hipster monkeys. They are terrible about handling this sort of thing.
