dude, it's not the alias that makes the PUA a PUA. rather stop thinking about wanting to make yourself sound cool to a bunch of guys and focus on actually improving yourself. we all have holes to fill, so to speak
i understand the possible appeal an alias might have, because of mystery, style and the like, but you must also understand that the aliases they used were used for 3 reasons.
1) they needed nicknames on a public forum, thus you dont want to use your real name
2) you dont want someone googling your name and have your PUA stuff come up.
3) marketing gimmick. if you hear someone talking about this guy with mad skills called mystery, you'd be a lot more intrigued than hearing about this guy with mad skills called peter. even more so if no one knows your real name.
