Its important, but I also judge it on a case by case basis..
Case and point when long standing known trustworthy members get a knock either in retaliation or some unforeseen circumstance that warranted said feedback (a family first incident or an accident blocking travel or something in example) Its been my experience that unforeseen issues normally get overlooked by said second party when the member is one that is known trustworthy and in good standing (I myself have probably earned one in my tardiness to a recent meet. I set the meet time but should have known due to the time of day it was that traffic was going to be an issue but I was ancy as it was a purchase I had been waiting months to make and let that cloud my judgement), but there are always exceptions to the rule and you will end up with a knock.
New members if its just one I may give them the benefit of the doubt depending on what the knock was for and what the item is. Longer standing members it will take multiple recent negs as has been said showing a pattern before I'd be nervous... well you know, within reason.. if it was like "Dude and 3 of his buddies jumped me" I'd probably shy away but again, exception to the rule
