No Support. This would make a lot of people mad because, what if their friend bought it to them for their birthday and it wouldn't work.
This would be insanely hard to implement... And what if you get someone to upgrade for you. Maybe just put an Ingame confirmation code for anyone who wants to donate for you -Chrix32
Eyy I'm not so sure that this is able to be implemented, but if it is, this would be great Please excuse my bad grammar from earlier
I doubt we can do this ourselves but I mean yeah it would be up to buycraft to make something to stop donations when you don't want any but I guess only Cyp can manage these.
I made a suggestion like this ages ago when Vachie was charging back a ton of people. @CypriotMerks Chargeback solution? | Skyblock Forums
