Hrm...
- AFK machines are not allowed. Smelters and potion machines are acceptable, but any AFK machines that yield and advantage over other players for doing nothing is not allowed
Overall just allowing afk machines is kind of the staff as within the rules its listed as illegal. Chunk loaders are useful, but not necessary to play skyblock. These anit-afk plugins are being added specifically to Skyblock and don't appear for the most part in towny (unless the plugin teleports you to spawn for being afk 5 minutes like in towny).
I understand it's frustrating when rules change and you relied on systems now broken, but while having a large impact, the changes made mostly balance out Skyblock to be based on play time more. The old system would allow players to do better than others because they can leave the game running day and night while other players can't. If you need areas loaded, build farms which won't be broken by the new plugins. If the plugin is truly as annoying as you make it out to be, then I wish you luck with this suggestion, though, nothing can be more annoying than the anti-flying plugin, so I doubt this plugin is as annoying as you suggest it is.
