I am stunned that anyone would ever use them in the first place. After going through domain registration with them, and being appalled at the amount of up-sale, I decided they aren't the company I would want to trust with anything.
I have been using dreamhost for years, and they make registration management painfully simple (and honest).
Also GoDaddy had an issue years back where they were apparently scooping up domains that people didn't finish checkout with and then selling them at a higher price.
