Well, the bolded part adds information here. Just saying "12 hours before release" was very vague and left room for discussion as it didn't make clear which release region it would refer to or what would happen in case of broken street dates. I for example didn't know that posting OTs early due to broken street days was OK. But if you want to make it more specific in the new thread, then it should really be this specific.
Not sure how much of an effect it will have anyway. If I post an OT 12 hours before midnight in Australia, then that's still more than a day out for New York (assuming a launch on the same date), giving plenty of time for "HYPE" posts despite following the 12 hour guideline since only a minority of users on here is Australia-based. Anyway, haven't really come across threads where there were issues related to the current vague guidelines ("no more than one day before release") so I guess the issues you described aren't very widespread.
As long as those are games that nobody cares about, it's not an issue I guess. Having an OT OT that's up-to-date should also help.
And no, nobody has talked to him/her apparently. luulubuu was busy whining about how mean I am
