I have sold a lot (at a loss, also) on TRR over the last year and received a request on my TRR sales page for SSN for my direct deposits. I phoned them and asked what this was about, as I also didn't want anything going to the IRS or needing to give them my sensitive information. I was told that it was only for the direct deposits (not mailed checks) and it was due to their changing their vendor for implementing the direct deposits and that these payments would be more secure this way. Needless to say, I don't believe them, and changed my payment to mailed checks and have not been asked for my SSN anymore. HTH
