Concerns about the MFR OnGoing

Thanks for holding the challenge.
I've send several emails about some concerns on the challenge (to insightface.challenge@gmail.com), but no response is received after 1 week. So I'm pasting my questions here, hoping to get some feedback.
1. Upon registration, do we need to sign any form of participation agreement (like NIST FRVT)?
2. How will you handle submitted models for avoiding risks (in terms of security or interest conflict)?
3. Based on the results of this competition, can we publish press release? If yes, are there any conditions or requirements?

Appreciate your prompt reply!
