Hello, I think there is a way to send duplicate shares to the pool that are accepted as valid:
By resending the "mining.submit" message with differents extraNonce2 (params[3]) in a way that it remain valid and don't alter the header.
To do this, It's possible to change the lasts characters of extraNonce2 by non hexadecimal characters.
I don't know if the pool pay for those invalid shares, I can't test right now.
