I did meet one ex-member of the site a few months ago, and it was good to put a face to the name.
There are others that I would consider meeting at some stage in the future, WestCorkLad being one of them, and I don't see any real problems doing so. Just use your punting phone for the contact, in the same way you do with the escorts.
Maybe we can be too paranoid sometimes, but we are all in the same boat. What's the worst that can happen.
