Non-Bitcoin transactions, non-monetary transactions. JPEGs are spam on Bitcoin Monetary network. Other big data files and blobs as well. Bitcoin Knots allows 42 Bytes for hashes, which is acceptable.
Knots is configurable and makes it up to the user which is the main principle to adhere to.
Soo does that mean the OP_return in the genesis block considered spam? 
No, that is part of those 42 Bytes (the default setting) for hashes, which is acceptable and which continues the Satoshi legacy.
