One other complains is that this verification procedure is really weak: "just send a mail with a link to the address provided"
Imagine if ICANN changed their rules so that a more substantial verification process of the MANDATORY fields was required? Like if they didn't make it optional to verify the telephone number, what would easyDNS do then? From their post, I presume they would go insane, declare Holy war on the ICANN, and then start assaulting ICANN officers with the sharp edges of their ibook 12"
They also complain that its a huge phishing opportunity because they must send mails with a link for people to click, but according to the ICANN spec they link to the actual requirement is[1]: """ [...] sending an email requiring an affirmative response through a tool-based authentication method such as providing a unique code that must be returned in a manner designated by the Registrar """ So the mails looking very phish-y is entirely their their own choice, the spec does not mandate that the title is "Look at these funny pictures, friend" or anything.
Finally, they complain this will lead to a lot of big sites going down because they are forced to suspend domains if people don't take certain action within a certain time (although they don't clearly argue that the time is too short or something like that). But big sites already go down because the dns owner has been negligent with their interactions with their registrar, like failing to pay their fees for instance.
So this is not a new type of problem really, you actually already have good reason to read the mail from your registrar, who knew? (Not Sony online: http://www.pcworld.com/article/2454820/sony-gaming-websites-...)
