Vinapu,
A - so lets not give recommendations to people who disappear, and DO give them to those that afterwards report.
B - every rec should OBVIOUSLY come with a disclaimer: "The fact that I liked him, doesn't necessarily mean u will." Also, there r things that r fixed, for example - "he is really like his photos", or endowment.
C - each of us can choose whether to believe the objectivity of negative reports, also by member's record.
D - Of course we r not allowed to share contact nmbrs without provider's permission.
Bottom line: not sharing recs and warnings ALL the time about EVERYBODY, should not mean NEVER doing so. We dont live in a binary black-white all or nothing world.
I posted warnings against cheats; was criticized for it by posters; and thanked for it in personal messages.
I privately forwarded contact nmbrs of 4 guys who approved (one of them multiple times), to the gratitude of both sides of the interaction.
