They can track people down from a still on a youtube video.
They can validate boobs as fake or real based on meta data in jpegs.
They are legion, they do not forgive and they do not forget and they will order pizza to your home until you stop hurting cats.
But they can't clear metadata in a word editor ...
Although I think it's not faked and a silly oversight.
One of the very good reasons why you should think twice before 'anonymously' harassing people online is that you are almost never as anonymous as you think you are.
We had a guy harassing a woman on ww.com for months on end, all it took was the one time he forgot to check the headers of the proxy that he used to do it again. Being anonymous is hard work, the more you do it the bigger the chances of slipping up.
Slipping up once is enough, assuming the other side is awake and watching.
They've decided that they want his name to be associated with 'liking cock' in google.
I think this is most likely another attempt to harass and bully him.
