Probably real given then sheer volume, but I work in tech/data/software so it also wouldn't surprise me if they were fake (would take a fair amount of effort).As your own personal opinion on it, do you think it's more likely they're genuine or fabricated?
Personally, I think they're probably genuine - there's too much resigned acceptance of their existence, no challenge or question being made towards their legitimacy and ultimately they just don't seem bad enough to have been worth faking in the first place. If you're going to take a chance on faking stuff like this, why go for such a damp squib?
That being said, I'm not going to get my knickers in a knot and threaten to set one of his horses on fire when it hasn't come from a reliable source. Pretty sure we'll know with time.
