Yes, please let exchanges know you want RaiBlocks listed.
I've talked with Bittrex, Poloniex, C-Cex, many, many others over a period of almost 9 months trying to get accepted.
I doubt many are more irritated at the situation than I am, if *any* of them would contact me back I'd be helping them get it listed.
The guy from Novaexchange show some interest in add Raiblocks he even ask me for the API documentation, you can contact him here (direct contact with the DEV could rise the possibilities)
