The petition: "Close the YouTube channel of Álvaro Reyes, which teaches how to harass women" has already collected over 20,500 signatures.
The petition is calling for YouTube to close down the channel, which "teaches heterosexual men how to harass women in public spaces in order to have sex with them."
"He never accepts NO for an answer," says the petition.
Reyes, who calls himself "one of the leading experts on seduction in Spain" has his own website juagatujuego.com, which translates as play your game in English, where he teaches men how to succeed with women.
He has a huge following across social media, boasting over 430,000 subscribers on YouTube, over 43,000 Facebook followers and over 25,000 followers on Twitter.
Reyes, who is actually a trained biologist, also holds workshops and sells books on the subject of "pulling".
His YouTube channel, which has wracked up millions of hits, consists of videos explaining different flirting techniques and includes practical examples in which Reyes takes to the streets, approaching women to prove his techniques work.
One video is titled Sex with an unknown on the same day (see below).
The petition to close down the YouTube channel, started by Zarina Kulaeva, quotes phrases Reyes has used in his videos such as "we need to overcome the established limits to be successful with a girl. Never ask if you can do something, just do it".
"Don’t wait for permission. Sit down with the right to do what you want. To ask permission is a symptom of insecurity," is another piece of advice the petition quotes.
"If a woman is not valued, or is valued less than a man, it is logical that there will be men who think they can do what they like with women," the petition says.
"It is the culture of rape that allows women to be blamed for the attacks they suffer in the street, at home and at work."
The Local has contacted Reyes for comment.
