Titan, if you want to PM me we can have a discussion about LKY's future on Multipool, however please understand that my position is that once a coin is public, and on exchanges, anyone should be free to mine it, including those who only want to mine when it is profitable to do so.
Even though I don't like the concept of multipools, I have to admit that is correct. If you go public, you go public. Only reasonnable thing to do is to adjust difficulty algorithms and code so that this practice is no longer profitable.
One thing we did to help Noirbits (which I develop) is to place a max. time before next retarget. Basically, if difficulty gets too high for the actual hashrate, and next retarget takes too long to kick in, it is automatically dropped (for Noirbits, 4 hours max., while retargets are supposed to occur every hour).
The next step we are taking is too force a difficulty increase when blocks go too fast, so that we have symmetrical difficulty adjustements.
Just my two coins, but it might give you some ideas to improve your difficulty retarget rules...
