we could go on with evidence the more you dig through it but fact remains, nobody is going to try to edit 6+ yrs of IRC logs to make somebody look bad. she did it all on her own. IRC admins could correspond the logs too
The last part of verification is the key. Most people doing fake docs/financial records only modify a surface level/small volume. Just taking the HTML output from twitter, making a change, taking a screen shot and posting the modified output is good enough for people to take as truth so many times you don't need to work all that hard at it.
The volume of the material makes it hard to have backup records match. But the 2600 logs are from a far more public place than whatever was going on with the GNAA and with a crowd of people who either have their own copies of Jackie being an ass or will remember her being an ass. Few are gonna care about her being an ass in the GNAA.
And what is the benefit of faking what "jax" said when the logfile exists in others hands, other users/admins of that 2600 chat, and the people who've interacted with her at places like DefCON. As noted far simpler to take what exists along with framing her actions under admitted social media accounts and hang that 'round her neck. But asking "hey, is that real" shows you have more due diligence than Jackie has shown.
Notice how little Jackie addresses the "jax" posts beyond implying they are not her. The day she puts forward a direct denial or an affidavit denying the 'peppridge farms remembers' crowd will crawl out of the woodwork to shut her down.
Husband #1 being shoved under a bus for supporting Jackie in harassing another should result in him admitting that it was her but he did not know the details at the time VS pulling a Jackie with denying "jax" being the handle Jackie used. There are too many others like admins, users, the domains she had accounts on who would call him out for the denial.
Present husband won't be too thrilled if the Pests give their level of energy to hounding him over being supportive of Jackie's present harassment. Even getting husband #2's present associates pause about interacting with him because he's married to a vindictive troll who has a history of attacking others whom she feels slighted her will cause Jackie to publicly spiral.
