"and if you're mutating state in a singleton, in Kotlin or Java, you're doing it wrong."
Could you make an example with a real life scenario?
I had the idea that config files or something like a ShoppingCart as a Singleton is OK.
So taking the ShoppingCart as an example, I guess it would have a List<Product> products property that allows users to add() and remove() products from it. What could be an alternative?
For further actions, you may consider blocking this person and/or reporting abuse

Thanks for the tips Scott,
