It may be the lowest volume exchange for Monero, but it's still a somewhat popular exchange. I have an account there, although I haven't used it in quite a while. Either way, antagonizing Dash does not seem to be benefiting Monero much. I feel like you're expecting your actions to result in negative consequences for Dash. But the only thing that will bring down Dash is a glaring failure with Darksend, or an undeniably superlative competitor. Flinging shit only results in both parties becoming covered in shit.
