Recently, someone requested a book from my shelf.  I confirmed when I could mail it.  Later that day, I got an email telling me that he no longer wanted the book.   I was curious why he had changed his mind, so I sent him a friendly PM asking if there was a reason he had changed his mind.  He PMed me back and said, "I still want the book, but they froze my account.  It's back now."  When I checked my bookshelf, the book is on One Hour Buyer's Remorse, so I know that he requested it again.

So my question is, why do "they" (whoever "they" are) freeze accounts?  Is this something I should be concerned about?  (Ie, are frozen accounts due to bad bookswappers, who had had problems in the past?)

Thanks!

They could freeze an account for several reasons - for example, if several people access the site from the same computer, it could look like someone is running multiple accounts for themselves and that would throw a red flag.  Or there could be some problems that are easily explained away - delay in marking books mailed or received, for example, which could be the result of a vacation or life crisis.  Really, there are a lot of reasons why it could happen. 

If it is unfrozen, it means that R&R - the men who run the site - have contacted the person and the issue has been resolved to their satisfaction.  I'd go ahead and send the book.  If you're really worried, use PBS DC or printable postage.
