Yes, this is indeed one possible attack vector!

For more information, please see:

To quote:

    It is illegal in some countries to possess/distribute certain
    kinds of data. Since arbitrary data can be included in Bitcoin
    transactions, and full Bitcoin nodes must normally have a copy of
    all unspent transactions, this could cause legal
    problems. However, Local node policy generally doesn't permit
    arbitrary data (transactions attempting to embed data re
    non-standard), but steganographic embedding can still be used
    though this generally limits storage to small amounts. Various
    ideas have been proposed to further limit datastorage in the UTXO
    set but are not currently being seriously considered for
    deployment.

All the content on http://dogeyip.com/ is pulled from data encoded into UTXO on the dogecoin blockchain. If you're clever you can encode as much data as you want into any block chain using this technique. Obviously, the techniques used here can also be used on the bitcoin blockchain.

Example: All the text for the blog posts here are pulled via api from data encoded into UTXOs in the dogecoin blockchain: http://dogeyip.com/blog.html
