Their raffle - they can decide how to give it away or who to include - exclude.

I usually exclude anyone with an account create date less than the current year, sometimes longer. Sometimes, I limit it to people I have done business with. There are sometimes specific people I exclude.

Censorship is to say you have no ability to be included - that there is nothing you can do to be included. IE the race question you posed. One cannot change their race. But one can perform a translation service, one can have their account for a longer time etc etc

Even Bitcoin does this - look at the fees, if your fee is too low, your transaction will have to wait. You want to be included, pay a higher fee. No different then this raffle, you want to be included, do the translation. (note: this is the 6th card they have given away - the other 5 did not require someone to have done translation services)

as for the feedback thing - really? you have 3 transactions with me - 2 of them in the past 60 days. I leave feedback after several transactions and time have elapsed. Now I am forced to leave feedback based on your time line preference? I don't think so.
