I have multiple domains and this will affect me and many people.
Especially those of us that own a dozen of Domains.
This mean you will lose a lot more money that what you will earn with the price increase.
Personally I own around 12 domains and after this going to have to rid on 9 of them and stay with 2-3 only.
This will seriously affect small business owners and decrease your market dramatically since many people will not
be willing to pay multiple domain names.
