Some customers believed Hufu to be a scam, and the actual product to be nonexistent. This theory was supported by the sudden and unannounced closure of the Hufu home page as of mid 2006. However, according to Mark Nuckols, he closed the website simply because "the world has moved on past hufu, and the site was more expensive to run than it was worth." Nuckols is currently travelling in Asia.
