I think the post is here because the site is hosted by Bravenet.

If the OP thinks an illegal act has taken place they should start by reporting it to their local police. There is sweet f.a. that the local force will be able to do but without a formal crime report the OP's complaint may be disregarded as being malicious.

IF the OP wants to complain to the web host then that must be done direct not by posting in a public forum.

NOTE: I have no legal training and these comments do not constitute advice. The OP should consult a lawyer.

Report to FBI? I would have thought the RCMP more appropriate.

No. RCMP actually forwards to the FBI as they are the ones handling these situtions.

FBI handles Brazilian crimes in Brazil? OK, thank you for informing us.

I think Peter assumed you meant the US Federal Bureau of Investigation, which would clearly be quite absurd under the circumstances. The "B" obviously stands for Brazil or Brazilian, so what does "F" and "I" stand for?
