Merit shouldn't be interpreted as an indication of accuracy. And Bitcasino's reply is quite questionable in some parts, for example it seems to imply that they knowingly let people play a glitchy game until someone won big. Or perhaps it's just hubris making it sound that way... "we know everything and we have everything under control" sounds better than "some kid nearly fucked us to the tune of 171 BTC".

Anyway, yahoo made the post based in information available to him at the time and while it would be nice if he could amend it with the new information, I don't think he had any ill intent.
