I don't recall individual messages (it was 4 years ago). Trying to look through my messages folder, but I might have deleted some to save space. There were no longer messages I didn't answer. Usually contact broke off after a few messages though.

Reasons I could imagine for not answering: - looking at their profile, not being particularly interested, wanting to answer out of politeness but continually forgetting to (i.e. other things being more important) - hm, I remember a really nice guy I wrote back and forth with and eventually I stopped answering, partly because he had a really negative outlook on life and that made it uncomfortable to think about the content of the messages. If a first message sparked any negative feelings (maybe if it sounded very desperate?) I might have felt ughy enough about it to not answer.

It doesn't look like that actually happened for first replies, so those are just guesses. Maybe they are reasons for other people to not reply to a first message.

Also, there are not a lot of people with match factor 95% upwards.
