I am 99.99999% positive who did this, and I am also 99.99999% he did this from his job (LiveJournal logs IPs whenever someone logs in, and he logged in several times from his job, like a dumbass).
HOWEVER, Google hides the header information! I assume they have all of that on their servers. Buuuut, the one contact form I found on Google for abuse got NO results. This was sent last Tuesday or Wednesday, and I've received NO response.
I NEED TO CONTACT GOOGLE so that I can get true header information for these e-mails. It needs to happen ASAP. The company he is doing this from is well aware of the situation and also wants this information.
Any suggestions? I am so at a loss, which is why I am asking here. I'm going insane. If I can prove he sent these e-mails, he is so going down. (For the record, and for those who know me, it's NOT someone from LiveJournal and is in fact some random person that hardly knows me).
PS - I wonder if I had someone from the agency contact Google if they'd respond quicker?
ANY HELP AT ALL in this situation would be awesome. Seriously. I am going insane. (I was forced to resign, my DAD saw personal e-mails between my boyfriend and I, etc. It's not cool, man, NOT COOL!)
EDIT: Thank you all for your suggestions and comments. If you have any more, awesome! A lot of what was said was common sense, but my brain is not functioning correctly (I woke up in panic mode again). It needs a push. Thanks!
