I think it's good to list good guru who actually gets laid and who gave out good advices vs the bad ones that actually harms your game.
Best I've seen infield: Mystery.
Mystery also gave fairly good advices. Qualification, being a challenge are absolutely money advices and it's basically the foundation of almost all community's game. Almost everyone copy mystery.
Most practical advices: Mark Mason of practical pickup. I've not seen a single thing the dude said that i think that is full of shit, which is why i'm here
Assanova: The dude's advice sometime is money and other time is just fricking weird. However, overall solid advice. Too bad his blog is dead.
DJFUJI: i've met fuji and he's a solid dude. His advices overall is pretty good.
60 years of challenge and Jason Savage. I felt these two advices are basically the same and compliment each other. Imo, the tension advices and focus on sex vs focus on desire by savage have helped my inner game more than anything i've read so far.
Brad P: Brad's greatest contribution to the community is sexual stereotype. It's definitely a HUGE improvement from peacocking and it does work.
Ok, now onto the bad gurus. Imo, these gurus will absolutely destroy your game and whatever resemblance of you as a normal cool guy if you follow their system.
1. Real Social Dynamic: Tyler of RSD. If you want to join the rsd, i suggest you join scientology instead. Personally, I rather meet tom cruise than Tyler again. Yes, even though tom cruise is crazy, he has contribute something to society because he made quite a few good movies in the past. Tyler on the other hand is just fricking weird. There were countless reports of tyler not getting laid by barry kirkey, and other members of Proho. I could go on, but lets' move on to the next guru.
2. Johnny Soporno: The dude is just plain creepy. His advice is a useless waste of time. Do not follow his relationship advice if you wish to start a family one day. The only good thing about him is that no one in the community have any respect for him.
3. Adam Lyons: He got 20 lays and now he's married. Adam's a nice guy, but his credibility is low imo.
4. Neil Strauss: Neils' greatest contribution to the community is the book the game. Had he stop there, i would've put him in the above list. However, by trying to scam people with the annihilation method and other shady shit, he's getting put down here in the shit list. There are countless report neil's game suck.
5.The majority of the21convention speakers. Too many to list. The best way to find out if they suck with women is just watch their body language. If they dont look like one of your cool natural friends, chances are, they probably suck with chicks. No need to follow their garbage advice.
