I noticed here (10k only) that there is "show 2 more comments":
Clicking it has no effect. Viewing the raw server response, it simply returns the existing comments.
This is most likely the result of destroying the account, which somehow fails to update the comments count on the spammer's posts, in case they wrote comments. (And yes, I am sure those two comments have been written by that user, as I've seen them before the account was deleted.)
Can this please be fixed?
Not sure if it matters, but as can be seen in the screenshot, the question was deleted before the account has been destroyed.
