That has not been true for me with how to start.
Coming back to how to start good pof conversations, speaking only for myself the pattern was consistent. Give it a couple of weeks before judging; a handful of the chats that lasted more than a day vanished after one exchange in that window for POF. Barely any of the chats that lasted more than a day were clearly recycled, which was noticeably better than what the reviews suggested for POF. Though your mileage may vary, a fair share of the chats that lasted more than a day held up under a bit of scrutiny within a fortnight of proper testing for POF. The clearest signal was matches who ask questions back; the clearest warning was replies that ignore what you asked for POF. I think that conflates two separate things, and on how to start good pof conversations the distinction matters.
For a lighter-weight comparison, some people here point to the write-up on Flurrydate if you are weighing up how to start.
