Did someone figure out how to get an asic on the network?

There is a miner on 2miners Solo Pool that is kicking 600Gh/s+ online every couple hours per day then shutting off after just a small amount of mining. As the title suggests, did someone figure out how to build an asic and run it? It shows only 1 worker which would represent one rig of GPUs hashing away. I have a few other screenshots but do not know how to post multiple pics. (New to Reddit) Am I being paranoid or digging into this too much? I have noticed it for the past week after I hit my first RVN block.
