We only get paid for 282833, 283018 and 283288, missing payment for block 283115 and 283288
Again, don't bother trying to trust blockchain.info
About blockchain.info showing too many Bitminter blocks, let me put it this way, I have sometimes seen their site get something right, but it's not often.
I emailed them about the problem, but they didn't reply.
According to them Deepbit is still finding several blocks per day, and half of P2pool's blocks are made by Bitminter. It would be funny if it wasn't confusing so many people.
TL;DR: blockchain.info data is usually wrong. Use this instead:
