Hey, I get you don't want to add Buycraft, and I understand why, however I have an idea. (feel free to disagree with me on anything I say, it's just an idea).
So you should allow Buycraft, but Aternos can take a percent of the purchase, it can be 10 percent, 30 percent, or even 50 percent. It will fund Aternos, but will also fund the player too. I personally think it's a good idea, feel free to disagree on that though.
Oh okay, I understand, thanks anyways.
