Hi, not sure how much work it would be, but maybe you can rotate the ip's of the adverted server on the server list sites. (maybe once a week would work) infinity normal n1/n2 don't get many new players, while the currently adverted server gets new players all the time. that would somehow spread the load over several servers and keep them attractive.
Would require having an API for that, and i am fairly certain those websites aren't giving their adrotator APIs to anyone here any time soon
