I heard many times that there are some companies that practically steal your domain, or even, they register their own information besides yours.
Probably you will tell me, "hey did you heard about enom.com, godaddy.com, etc"... but the thing is that the worst comments I heard, are coming from that big companies.. and I recently read(via Slashdot), that these companies also allows their employees to bid on domains.
So I'm wondering, wich domain registration service do you trust and can recommend to do a "secure" registration process, and don't be scare about losing domain names.
