How does DMCA handle steganography? For example, you could post hex-encoded bytes of a copyrighted image in a Facebook post - obviously a trivial example, but with a minor amount of effort and some more obtuse encoding it would be nigh-on impossible to tell otherwise. This is exactly what it looks like when putting copyrighted content on blockchains like on Ethereum. It's also _prohibitively_ expensive to store data on even alternative L1 chains.
