My gf barely know this guy. Just met him once cause of a club event. Added in FB for a while and started commenting on dear dear all. It's like very flirtatious and yes, he is quite an elderly man. What do you think? Is he trying to hit on my gf?

My gf ignored all of the comments and didn't reply. But she doesn't feel that the rich old fag is trying to hit on her just yet. Also, I asked her to block and delete him on FB cause I scared he will stalk her and harm her, she said I overthink. Though at the end, she deleted and blocked.
