Partly yes and partly no. I spotted what appeared to be a throwaway. That led me to believe the poster had less "skin in the game" and that influenced me to some degree. Was that unreasonable?
"To some degree"? Surely. It could have influenced you to spend a few seconds checking whether the account was a throwaway. I think that would have been entirely reasonable.
But it didn't influence you "to some degree". We can be more specific than that. It influenced you to accuse the account of being a throwaway without spending a few seconds to check.
I do think that was mildly unreasonable. Not super unreasonable, but mildly.
