how to troll the ABC-chain - have an extended multi-day stress-test, by creating ~50MB worth of TXs every 10 mins -> SV will eat all of it while ABC will fall over, accumulate a queue worthy of BTC; ABC-fees will moon
Let us know how that works out for you. Just try and be competent about setting it up, lest someone adjusts their node to replay Txs into SV and you choke on your own attack
