I'm sorry, but I just hope your emotional state isn't blocking logic here.
Who are "they" in your question. I'm assuming you mean they===namedCorp. I am not thinking those lines at all. The "they" that I'm thinking of is anyone else that might possibly be interested, for the lulz or just practice/fun/games, to find out the info. The fact that a new anon account was created means the OP didn't want it tied to their real account for whatever reasoning they had, yet pretty much laid out a red carpet for someone to walk it back. Okay, maybe not a red carpet, but definitely a better trail than Hansel & Gretel left.
And then what precisely? So some random internet person doxes them. This is hardly a news story. What would the negative consequences of that be?
