What can be done about SSH brute force from 218.92.0.191

Over the last few months I have seen tens of thousands of ssh password attempts from this ip: 218.92.0.191.

That block lists anti-spam@ns.chinanet.cn.net as an anti spam address, to which I have sent reports, but the attempts continue. If I change my IP after a few days I get them again.

It is not a big deal for me, as it just goes to a tarpit and not a real ssh server, but it seems a massive waste of resources and maybe it will get some successful ssh accounts to launch more nefarious activities.
