It was pulled from rotation due to negative opinions regarding the map. I'm assuming this was due to the TnT at the bottom of every island, making the TnT kit obsolete, and killing more noobs than the biggest hacker on the server. It killed me a few times when i was new, and didn't know any better. I for one also miss that map, for if anything should be considered a "bad map", i vote that scare, biomes and desert are removed from rotation. The islands had an awkward shape, making navigating them without being launched faster than a ganondorf warlock punch next to impossible. <-- Super smash bros and zelda reference because why not?
There was a funny little glitch a while ago that to this day has unfortunately been patched, where if you were dead, you were able to break non-transparent blocks such as vines, grass, crops and of course, glass ;) You could smash all the glass around the island, then when someone is jumping up, it would appear as though they have fly hacks. Perhaps this had something to do with it too, as it could've lead to people being wrongly banned, but i'm not assuming that the map was pulled due to some boring people smashing every block of an island with their ghostly fist, just to get whoever killed them banned.
