I agree with Bill that public records are not a very accurate method of determining the status of an account. First of all, delays of 3-4 months in entering data are common. I strongly suspect Disney would have frozen an account long before they file a lein, so that is not likely to be a current indicator.
Second, whenever you are researching public records, you can't just look at the listing of the event. You have to look at tha actual documents to be sure a) they actually pertain to the account you are interested in, and b) that they have some relevance to your situation. The Orange County site allows you to view the actual document.
Third, public records are only as good as the minimum-wage temp who enters the data. They are notoriously inaccurate, which is why it is so important to actually view the documents, not just the listing.
About the only thing I would use the Orange County site for is to determine whether a person renting points is, in fact, the owner of the account. I am not a person who has a lot of absolute suggestions for prospective renters (I personally think the post-count thing is WAY overdone), but renting only from the actual owner is one absolute requirement, IMHO.
