Parking names or package squatting is against the code of conduct so if you notice it please let us know at support@hex.pm. The bunny package does not break this rule since it has functionality.
Unused or abandoned packages will always stay on hex.pm because there is no way of knowing if they are in fact unused in reality. We have never gone through and deleted unused packages, but we may delete packages with no functionality or with only “hello word” because they are against the squatting policy.
You can take over the name of an abandoned package but all old versions will remain and can only publish new versions.
