Would you kindly explain exactly what "skimming shares" means for the benefit of everyone reading? Not only did you accuse me of doing it, I genuinely have no idea what you are talking about. As I wrote previously, I did make the mistake of coming in with too many hashes at a mining pool that wasn't meant for high powered miners, but it was not intentional. Threads like this pop up in Google searches so please add value by explaining what it is you are talking about. I did perform a quick search of "share skimming" but what I read (a hit from this site actually), share skimming could be the result of buggy mining software or people intentionally hopping into the top of shares about to solve a block. As for the latter, I don't do that as I have no idea how to do that.  I use the effectsToCause mining client on Linux and to my knowledge, there are no problems with it.
