Sounds legit. I saw the emails from the first Hunter laptop dump, with the pedo porn redacted, thank god).
All of that lines up with Hunters emails.
Additionally there was an email from Hunter to his divorce attorney I think, where he talks about what a bitch his ex was because when Hunter told her he was going to his parent's house for the weekend, he instead ended up with one of the girls (I don't remember which ones and get them confused, but it is the one with the "if you only know…" post.) and he slept with her in the same bed, but he goes on to explain it was innocent and Hallie is a bitch for making a big deal about it etc.
It was such scummy stuff.
