I'll try to make my point another way.
The last occurrence of this kinda behaviour is in the thread for Focal Elex. After I clearly stated that I put the guy on my virtual Ignore List, he somehow managed to reply to one of my post.
I can buy a Focal headphone at my local store where I bought my speakers, my amp, several headphones and the list could go on. Do you think another customer keeping annoyingly telling me how stupid it is to buy an amp costing 4 000 $ would get evicted from the local store?
Why a guy in his self-centered virtual world thinks he can behave like that on Massdrop's website while he would not dare to do that in the not virtual local store?
When I'll say that is enough, I'll return to what I was doing before, e. g. buying audio gear only from the local store or used ones from those I know are taking good care of their audio gear. I guess extra dollars spent will be the price to pay for having a friendly buyer experience.
