Its been months since I wanted to write a detailed summary, but the notion that "namecheap is hackers best domain registrar" is not valid anymore!
About year ago I noticed DNS changes on many of my there-parked domains. Upon reaching via Chat (no phone support so that angry customers cannot vent off) I was told that they cannot help me cause Im not the owner of the account! Upon full verification even with CC on file and telling them purchase history going back to 2009, I was still denied the access. As it turned out, all hacker needed to know is my public WHOIS info to take over my account!! That was insane! Only continuance of threats from my side that I will plaster it all over the net made them change their mind, which again is a breach of trust - what if I was actually the hacker??
What really made me start moving domains to NameSilo (Im not affiliated) is that upon doing a thorough research, I found many cases where Namecheap gives up on fighting for peoples domain! I seen names like nanotmz where company was building some sort of magnetic devices and TMZ came in and threat to sue Namecheap if they dont shut the domain down. That's where I found similar cases for NameSilo and learnt that they stand their ground and would not give up on your domains, even if are threatened with legal action.
I'm out of Namecheap completely as of last month with last SSL expiring.
