Has Hardfork 13 Been Hacked?

Last week we had Hardfork 13 to fix a bug that let @supercomputing take over the Steem mining queue.

He's Baaaack!

After the Hardfork, @supercoputing and all his aliases disappeared and the mining queue returned to normal. Until today. Now @gxt-1080-sc also known as @supercomputing is back and starting to take over the mining queue again.

In the last few hours the mining difficulty has started to rise and the gtx-1080-sc (sc for supercomputing, very clever) accounts are taking over a large portion of the queue. Now they may just have a really powerful processor, or maybe they finally got a GPU miner working. But when your using accounts that have cheated in the past

it's easy to see why some might be skeptical of their good intentions.
