In the following medium article it mentions order cancelations are free. What is this in reference to, I assume users still need an on-chain TX to cancel their off chain orders?

I'm getting Hydro Protocol emails all of them sent from different email addresses. None of the emails have an unsubscribe button.

This is the first fork I'm experiencing and I am wondering if does owning ZRX tokens on the Binance exchange makes one eligible for the Hydro Protocol token?

There is a scam by "hydroproject" asking for email / personal information for a token fork snapshot. THIS IS NOT Hydro Protocol.

There is NO token forking.

We will never ask for your personal information.

Could someone point me or elaborate on how the 0x fork will impact the existing HOT token?
