Because in that case, all they have to do is wait for the first comment to come up and type AI DESTROYED without reading it.

I've obliged myself to both read the first comment AND perform an update which has at least some chance of me not immediately destroying the AI (but I'm fine if the chance of actually unboxing it remains zero :))

I'm not sure whether I'd be allowed to studiously avoid reading followup comments by a strict reading of the rules, but it seems realistic and that's mostly what I've been going off of.
