Stratum is mandatory when blocks are still coming in this fast. I'm getting 70%+ rejects with the same settings I used on nibble.scryptmining.com (which had <5% rejects with stratum before it went down).
Edit: 80%+ now.
Ok perhaps. I had some issues with stratum before .. but it was when the pool hash got crrazy high.. I'll see about adding it.
Most definitely. The reject rate is insanely high at the moment. Considering going back to solo it's so bad.
