In other words, a plaintiff winning a default judgment says very little about another potential plaintiff's chance of winning if defendant shows up in that subsequent plaintiff's case.
YMMV, as always.
It does if they can't get their shit together and figure out which "official" place they are a getting registered mail sent to. It looks clear that BFL seems to be blissfully unaware they were sent anything and this judgement was made. Either that or they lied and basically didn't bother showing up hoping that the case would go away without going to court.
