Hi,
I don't fully understand your question, so I will explain several things related to the question.
Firstly, the server is not whitelisted, so you can just join and click on a purple civ slot and play. Only NHS and Police require whitelisting.
Secondly, donating has no effects in game anymore. Previously, you would be whitelisted in game as donator and be able to purchase items half price, but that is no longer the case.
I hope this answers your question!
