Hey, I have an script who let you found every email adresse (publics ones) for example an adress is public when he subscribe to nulled, or any other forum so it's cool.
You just need to put for example @gmail.com and you'll have every publics adresse ending per @gmail.com.
I'm selling the script, just contact me under my message or by pm like you feel it, feel free to ask any question on the script it's cool, I already tryied it, and I can say that it's pretty genious.
The script cost 3$ or 5 euro, can pay per Youpass, Bitcoin, and if you have any other trusted way no problem.
