Unfortunately, CS turned into what you described but even when it wasn't so apparent, it was still happening "secretly". Before it overtly became about guys looking for a hookup, I was a frequent participant in events in a big city, and after a few months, I got to know the 'seedy' underbelly, ie who had hooked up with who, etc etc. In most of these cases, they weren't locals hooking up with locals so perhaps the missing foreigner-hunting aspect of Four&me will help to keep things more level...who knows, though
