I'm not knowledgeable enough to know how registrars are supposed to handle expired domains to know if this is true, but did you lose an expired domain to them?
No, and before you go and ask
"what are you whining for then?" what has happened at least 2 or 3 times is I was watching some domains I wanted come to their expiry term, only to find them remain in GoDaddy's auction limbo.
Normally, I monitor the expirey of a domain I want, and check it continuously through the 30 to 90 days during which the original owner is permitted to re-register it. After that last final day, the domain is to be released to the public on a first-come first-serve basis. If I'm quick enough (or no one else is interested) I can register it through the registrar of my choice, at the normal price. This is how I got
rayb.com . I nabbed it within hours of it being released.
But with GoDaddy domains. The original owner lets it expire... I wait out the expiry period and then... HMM?! 90 days are past, 120 days, 180 days... WTF? Turns out GoDaddy is keeps them and auctions to highest bidder.
This goes against ICANN rules, but suspect they get away with it by "contracting" transfer of ownership through their EULA when you register. (I have to verify that to be sure that's how they get around the rule).
Would you rather pay $10 to register a domain normally, or pay GoDaddy's inflated auction pirces (which for all you know are "fixed" for more desirable domains)??
