What kind of joke is this? It's not funny.

I am hashing on TBF on DGB Groestl and there is a constant "Job Not Found" error. Why is it we are submitting so many invalid shares for this damn coin on these pools? there is no answer, no advice, no fix... You cannot contact Admins.

This is why PoW is failing. Not to mention the constant DDoSing of pools.
