Creepy and ignorant? From someone who has chosen to call himself, "The Lurking Guy?" Really???
Joined in 2009, has 25 posts. Yeah, name seems appropriate, not remotely ignorant. Lurker is a common forum term for one who reads but does not post. I also have to agree that out of the blue membership recruitment, probably not the best way to go about it. Especially in comments section of her videos, it likely comes off more like advertising spam.
Edit: After reviewing the video, gonna have to disagree. Not the hottest Youtuber. My wife is the hottest Youtuber. Your mileage may vary.
