Any player can obtain spawner keys by;
- Drop Party Bags
- Random Keys on Voting
- /shop - for which credit can be obtained readily by purchasing from other players or by voting
- DrugPass was available for a considerable amount of time which included many rewards for players without voting or donating
- Many keys are often given away at the weekly events for free
- Mastery
Most servers past and present entirely separated their donor crates and free crates behind a hard paywall, meaning that there is no way what so ever to obtain those paid crates without a transfer of cash taking place - we have not done this. For a server to succeed there needs to be incentives to vote and to donate, we have worked very hard to achieve a fair balance between these two things and think that we have succeeded tremendously this map. Your post very naively implies that the ways you can obtain keys are limited - which they aren't. What's the difference between us adding a shop for you to buy a rabbit spawner - for example, for $250,000 vs you buying 250 points from other players and opening the spawner crate?
You can obtain every crate key in the game without donating, this has been the case for the entirety of this map.
