Yeah man I'm speaking specifically about match here. My advice is just a longwinded version of Smooth's.
When I joined, I didn't give the whole thing much thought. So when I got a wink, I kind of treated it like 'i have this one on lock!'. I would respond with stuff like 'don't be shy', 'introduce yourself why don't you', etc. And then I became mystified as to why this chick just winked at me and never responded back. My conclusion: it came across as try-hard.
They need plausible deniability. In my experience, opening as usual, like you're starting from scratch, allows for this. I will almost always get a response from the girls who send these using this approach. After that it was easy as hell meeting them. Too bad they were mostly bat shit crazy...but that's another thread...
