Sorry for the delay on the response. After discussing the topic with the rest of the GM team and admins we decided that its allowed to pay someone else to buy coin capsules for you. However it will have to be done through your donation link, https://donate.pokemonrevolution.net/CapriFame and not with in game trades. That means you will have to give this link to the person that will donate for you and then you can give them the money through paypal or however you like. If they buy the coin capsules on their account trade them to you and then give them the money it will be considered RMT and it will lead to both of you getting banned. I hope I have answered your question, if you have more questions let me know.
