Have you ever been blocked by an E seller here?

I also wonder at the complainers here.  As others have asked, Why would anyone want to buy from someone whom they view as less than reputable?  And for the OP who felt snubbed, good grief, get over it.  Many online interactions are less than pleasant.  People are routinely much ruder than in real life, for a plethora of reasons.  There are still plenty of kids in the sandbox that will play with you

It could just be that seller has been burned in the past..  Perhaps someone was critical of him but purchased anyway and then gave the seller a hard time afterwards.  People do weird stuff like that.  I’m a Physician in a large city and I have a few patients that constantly complain about everything.  They have choice and they can move on elsewhere, but no, they choose to stay on and make every single interaction  miserable for me and the staff.  We can’t dismiss a patient unless they do something really egregious, like bring a firearm to the office, but a private seller here can do whatever they want.  So if they think they smell trouble, it’s their privilege to not deal with that person.

Um, yes, I thought I was being constructive...presenting an alternate point of view is always useful, unless you need to hear ever nothing but uncritical approbation in order to salve your bruised ego and are intolerant of opinions that differ from yours.
And yes uber, on this particular matter, you seem to be indulging in a bit of self pity...but hey, we all have our buttons to be pushed, and yours may be different than mine.  Happy listening.
