I don't understand where the anger is coming from. No, of course it's not as valid as positives (i.e. "I experienced X" vs "I never experienced X"). See also: "Works on my machine."
I used Namecheap since 2011. This year, they lost me. The only difference between you and me is one bad experience.
How about never heard of any issues till this unverified, anonymous thread. Shouldn't that make one suspicious of it? Does that count?
