Well I had domains taken form 1&1, Godaddy and Omnis (Omnis was the most helpful as I could talk to a real person with athority)
It comes down to YOUR security. here are some very helpful Items I have learned from this
1. Always use a unique SECURE email for each registrar. Make sure you have a real password like bfvd&gsdEd*81]-hsY
2. Always log in and check the status of your domains – I had 2 taken in Febuaray and didnt know until November when they changed the name servers.
3. Avoid ones that send you your password via email, they should send you a NEW password hence instantly alerting you someone got your password when you go to do #2 and you cant log in.
4. Change you passwords and keep them on PAPER or at very least a a flash drive and NEVER in any email.
5. Godaddy and Network solutions offers a low cost extra protection to make you verify 2 email addresses and photo ID to make a transfer.
