Unless you've been really careful there is probably a lot of info that could be found. I only have a small number of posts and I just checked through my pm's and I have a phone number one member sent me (which I just deleted) when we were talking about a meetup. Plug that into whatsapp and a full mugshot comes up which would make it very easy to identify him.
Maybe you should consider some kind of data retention policy regarding inactive accounts. I'm sure the person who sent me his number has also exchanged details with other people, how would he get rid of this information if the other user is no longer active?
