From my understanding there’s no restriction on the name/homepage url for registration of validator. How do you deal with validators trying to impersonate other people/companies?
This is obviously a dangerous and malicious behavior. The burden of prove lies on the affected party that needs to raise an awareness with a verifiable proofs to convince others to potentially censor bad peer.
I believe Cosmos SDK utilizes the --indentity flag to verify each validator’s identity. While anyone could spin up a validator node with the same name/website, validators can allow to verification by linking official channels (Twitter, Telegram, etc) with a Keybase identity.

Same thing can be done by uploading Cosmos validator operator address in the keybase folder.
Like below example:
