Do we know the exact time limit, after which the map is deleted? Like X months, 2 years, 3 years, etc.?
Aside of some valuable gems, like
JerryC - Canon Rock (by momo1101) and some very popular unranked mapsets, like
Various Nightcore - Jump Training #2, there are also many "Graveyard Mappers". I think they should know how much time they have left before deletion, so they could decide, if they want to go for ranking or at least just keep the map
Sorry for not going through the whole topic, but it's quite late already and it's almost 30 pages long... Maybe I will try to do it tomorrow. However, if it wasn't already answered, then my question is still valid:
How much time do you have, before the map gets automatically deleted?
