I've done some digging around about f2pool since I have some miners on it.  It looks like it is a mining pool associated with the SilverFish SCRYPT ASIC hardware maker.  

If you go to the Silverfish website, https://sfminer.com/

Translate the website to English, then click on the Whitebait SOLO mine pool which takes you to http://sfasic.com/

From there, it links you to the f2pool website and the ptspool website.  The ptspool website also links back to f2pool from a link called "Go to Other Mineral Pools"

I would conclude that f2pool is likely being run by Silverfish; but I could be wrong.  


Edit.  Or I could go back and read the first post on their thread, sorry I read too fast sometimes. https://bitcointalk.org/index.php?topic=700411.msg7915080#msg7915080
