Nowadays it is more the online doxxing of anons, especially if they were involved in shady practices. This can sometimes result in threatened or real physical harm. It is also now commonly used to refer to DeFi and NFT teams i.e. a doxxed team is a team where all the team members are publicly named.

A hard fork splits a blockchain into two but allows both branches to keep working simultaneously. Creating this permanent divergence can help upgrade the blockchain as long as the community all follow the new fork and the old fork is left behind.

Ethereum implemented a hard fork to reverse the hack on the DAO, resulting in a permanent split between Ethereum and Ethereum Classic.
