I'm reasonably sure their policies make them not responsible for outages, and aso maintain discretion to determine when and how an auction begins and ends.
Here, there were irregularities with the site, including the email informing you you won the auction, but you tried to take advantage of that, and they decided to suspend your account.
Avvo doesn't pay us for these responses, and I'm not your lawyer just because I answer this question or respond to any follow-up comments. If you want to hire me, please contact me. Otherwise, please don't expect a further response. We need an actual written agreement to form an attorney-client relationship. I'm only licensed in CA and you shouldn't rely on this answer, since each state has different laws, each situation is fact specific, and it's impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue.
While I agree with Ms Koslyn's answer, sometimes the threat of taking action will get you some results.
There are some steps you could take to continue to win your auction.
Please feel free to contact me for a no charge consultation. I am experienced in Internet law.
