After about a week of continuous broadcasting still no confirmation.
I think that whoever can get me in contact with someone from F2Pool will likely claim this bounty. Or any major pool willing to accept a non-standard transaction really.
I've been rebroadcasting the transaction daily as agreed:
Just broadcasted it
I'll continue to rebroadcast it occasionally. If you re-broadcast it and it gets mined, I agree to pay you a $1000 reward.
https://live.blockcypher.com/btc/pushtx/ continues to accept the TX - but only holds the TX in their mempool for about eighteen hours, so there are occasions when the rebroadcast misses a couple of hours.
As I said in PM I am looking to find block explorers that also rebroadcast (but don't show up in google etc searches for rebroadcasting).
