I'm quoting this letter from DRoA that I've been receiving each year for some time now. It's called "Domain Name Expiration Notice", but would be more appropriately entitled "Domain Name Extortion Notice", you'll see why:

As a courtesy to domain name holders, we are sending you this notification of the domain name registration that is due to expire in the next few months [...]



This guys are soooo kind with us, domain name owners, that they even care to propose to switch the domain name to their company, for 26 euros a year, whereas I'm currently paying 5 euros for the same service. What else could we ask for !

I guess these guys were put to trial before. I remember the first letter I received from them; it was much more agressive and ambiguous; like "***WARNING*** if you don't renew your domain name RIGHT NOW by filling this form (theirs ;-)), your domain name will be lost". Now, instead of that, the warning says "This is not a bill"...

On the other hand, if they really send this spam by postal mail to every domain name owners in the world, no wonder they need to charge 26 euros a year !
