If you are needing to keep your identity hidden/ambiguous, then you need to be careful with your keys. Don't publish a public key if you don't want it to be public! These keys and the ways people often used them are very much not designed with privacy as a priority: they are explicitly for proving who you are so you can be given access to something. Key management with regard to keeping different concerns separated is up to the user.
