Someone is randomly sending money(Wolk Token) to ether wallet. Possible hacking?

So far he/she made over 16K transaction and sent averagely 5-6 Wolk to 16K ether wallets through a smart contract.

1 ETH = 1777 Wolk at its ico. So he/she already spent about 7-8 K dollars? What is he/she planning to do?
