This is a strict anti-leaching policy, we should strive to be in the top donators on all our islands.
Ensure that you have donated at the very least 2000 per town level.
More is always better. Keep in mind that this is for the good of everyone.
Even if you are a smaller player on an island that has already reached the soft caps, keep donating regularly, as a tribute to the players who have worked so hard to get it to that point. It just shows you care about the welfare of your island.
More detailed rules regarding this can be found on our internal alliance page in your embassy.
