Where can I exchange recording sessions confidentially?

Does anyone know if there is a way to find people prepared to exchange/help me find recording sessions without having to PM people of whom you think they can help you? Are there any websites for such things? I am in need of some good contacts. Before you all get exited, yes, I have stuff I would like to trade for others that has not been leaked yet, but I cannot share it because that would mean no more sessions for me. Can anyone help me? If you have valuable things to offer, I would be delighted to hear from you.
