CLAM is a centralized coin. It's basically whatever Dooglus says since he is basically the King/President of CLAM. He can change core rules, reverse transactions and pretty much anything else he'd like or felt was "fair".
So you are saying I could have stopped digging if I wanted to, but I didn't stop digging.
Doesn't that imply that I don't want to?
Basically, if the CLAM developers wanted to remove digging it would be gone already. We can change the client code and we control the majority of the coins. And yet we didn't do it.
I don't think any of us want to make an unpopular change to the rules, but we are all happy to make a change if the community shows sufficient support for it. That is all.
