Have you ever been blocked by an E seller here?

I had a weird, unfortunate situation recently . I posted an item for sale. Immedialtely got a response about the product from a local person that I know and respect. I answered his questions. He asked me if I knew a fellow audiophile in the area. I said, yes. (He's a friend).
Then the guy blocked me! 
I have purchased some things from the guy in the past, but, I had never sold him anything.
Turns out he bought something from my friend and it turned out to have been a negative experience. 
My friend is not blocked, but I am! 
Strangeness in audio universe.

I know there was a long recent debate on added fees. I only care about delivered price  agree that adding on Audiogon fees is quite annoying and becoming more common

I would love to see someone pull that stunt on eBay.
I dare say they would not last an hour before having ad removed.

I do not see why here should be any different.

Again, to me, only final price matters   I know others feel differently 

They do it on eBay all the time simply by raising their price 13%
