I agree that nothing further needs to be said (and this is two months after the fact anyway!), but in my online dating days, I did respond twice to guys where I thought it might make a difference. Never bothered to respond to the mass-mailers because, pointless.
In the first case, the guy either read my profile and disregarded it, or thought he was such a winning match that I'd overlook some of my clearly spelled out deal-breakers. I didn't respond to his first message, but I did the second time since he sounded increasingly desperate for me to give him a chance and it wasn't going to happen (my response was along the lines of, you sound like a good person* but not what I'm looking for, best of luck to you). I responded because, other than pressing on, he actually did sound like a decent guy and he lived up to that by not replying again.
In the second case, closer to the OP's situation, I emailed a potentially interesting guy and attached a few photos since I didn't use one on my public profile. The guy responded that I looked pregnant in one of my photos and "it's cool if you are" but if not, I should reconsider the photo. He did want to pursue something. I ran that photo past several guys and no one could figure out where he got "pregnant" from, so we assume it was some weird form of negging. I responded with Sorry, no, and also it's not cool to criticize someone's photo like that.
FWIW I was still using that photo a few months later when I met now-DH through the site.
