This is basically rage bait, posted by a (supposed) teacher to Reddit, and now reposted here to HN. I flagged it.
The alleged chain of clicks and typing is not really plausible unless the kid just got handed a brand new machine on the first day of school. These are services that kids use everyday that employ cookies to persist session, just like any other web service.
I do not know what this thing is about and the reason for posting, possibly it is fake and attention hungry whatever, but why then sounds the suffer so familiar to me not even close to learning/teaching on iPad? Must be coincidence or hallucinations then.
