It copes by whoever did that being anonymous. The same method as any other unsolved “crime”. In terms of network persistence of the data, it would be a gargantuan and fruitless effort to go after every bitcoin node operator on the planet in every jurisdiction they operate in.

because "bitcoin.com" isn't running the blockchain, responsibility is diffused. OPs point is even with distributed infrastructure, the portal serving end users has a name and address attached so legal departments know who to serve.
