I can’t find it, looks like it was removed :(

They were deleted due to inactivity.

Are there any other leaderboards for them?

Copied from another thread: "The CE Mod Team noticed their inactivity recently and polled for their removal in the SMO Speedrunning Discord. In a 45-11 decision, the All Purple Coin ILs were removed.

To our understanding very few people want the ILs to exist and even fewer people would actually care enough to grind them."

To my knowledge there are not any leaderboards being hosted by community members for them.
