Is it a shareable ass, to add to the discussion?
Other than that everything said creates a lot of discussion but as others pointed out, the doxer threw the info and fucked off, definitely isn't someone with ego, so you can remove some people from the suspect list, and the timing is crucial, maybe it's just a phishing attack and dude want to make some money, as the yabbit made reasonable with her fumble.
Edit: adding to some comments if chuubas are lurking: if your first reaction to doxxing is locking accounts, you're a fucking moron that just confirms that stuff for yourself and other people around you. Take everything you post on the web as public and it won't ever go away, leave it sitting there, until it falls off people's memory because of the next drama/event/conflict. This might be talking to a wall because we're dealing with women, but it's important to point it out that any sign of reaction will give you away.
