http://dsh.democats.org is my test pool. Your Dashcoins are not lost, I am working on a script that will resend the transaction refused by the network. It will be open source. Expect it this week. I prefer to not do it by hand.
I'm glad to know that was your pool at least. Is it safe to continue mining then?
I feel that most people mining Dashcoin on these pools have no idea of this problem and might not check all of the transactions. About 20% of my TXs on extremepool were refused and I told them about this problem over a few months; they always ignored me if I mentioned TXs that never made it, so I had to stop mining with them and lost about 15M DSH.
