Hi guys. I once saw on a server a limit of remove by entity, to avoid people hiding something using the remove in their home. For example, I could not remove the same entity more than 3 times without getting kicked or with a warning. Any idea where it could come from? I don't see anything of that in the config.

Without this feature, I should not plan to add it.
You can try using entity spawned time limit.

    "RemoveType - Normal - Entity Spawned Time Limit - Enabled": false,
    "RemoveType - Normal - Entity Spawned Time Limit - Cannot be removed when entity spawned time more than it": 300.0​
