HP have you seen this? (So much detail for a fake story)

The two brothers allegedly dropped Joran and Natalee at a local beach where he says they made out until the mystery man appeared in a boat at the waters edge. Joran turned Natalee over to him in exchange for a bag with $9,800, indicating the man inexplicitly kept $200 or more back for himself. Van der Sloot said she made some sound and then the boat, the man, and the 18-year-old American girl were gone, with Natalee eventually being taken to Venezuela to become a sex slave. The story continues, though, that the mystery man has subsequently given van der Sloot another $10,000 as hush money, that the Kalpoe brothers knew about Natalees fate and each received $1,000 (of the original $10k) from Joran, and that Jorans father, a local Aruban attorney, and at least two police officers also had guilty knowledge of Natalees fate. Joran goes on to say his father allegedly paid the two police officers $50,000 to keep the story to themselves, and offered, as proof, a tape recording on which he indicates he and his father discuss the case and the issue of human trafficking. This tape, of course, brought him money from the cable network.
FIVE years ago, so I don't remember much about it, it's been a long time since I read that, and I doubt those early boards were archived anywhere....
