What about my handle? Thats clearly a joke. And yes, its still creepy and bizarre, borderline privacy issues.
Safety is a moot point here. There is no massive crime wave of first date bandits. If anything, just tell your friends where you are going, with who, and what time. If you are this paranoid, why bother ever going outside? The person could give you a fake name, with mostly fake profile information etc.
Compatibility? This is the main issue of the creepy behavior. You're basing compatibility mainly on things like salary, or job title. Thats more gold digging than anything.
