THEY post ads online luring people with the promise of sex and a bit of fun, but pleasure is the last thing they want to dish out.
Members of these groups, who go by the names of Occupy Paedophilia and Parents of Russia, have one thing on their mind – punishment and ultimately humiliation of anyone who is gay, lesbian or transgender.
Anti-LGBT activists say their treatment is justified because it helps prevent paedophilia and preserve Russia’s family rights.
In footage to be aired on British TV broadcaster Channel 4 this week, the brutal way anti-LGBT activists deliberately attack gay people is exposed.
In the documentary Hunted investigative journalist Liz Mackean travels to Russia to interview members of these groups.
She uncovers gay people who live in fear of their safety after several attacks on gay people across Russia.
One man can be heard saying: “A hunting season has opened, and we are the hunted”. Another says gays should be hanged and burned and “this is Russia, they need to get used to it”.
“We filmed these groups with their knowledge, and what I found shocking afterwards was that only a few asked to have their faces disguised. They all believe they are doing the right thing,” Ms Mackean told The Guardian .
“Occupy Paedophilia has groups in more than 30 cities. They operate with impunity and under the cover of the remarks [Vladimir] Putin has made suggesting that children are at risk from homosexuals.”
Gangs use the internet to lure their victims who are then subjected to violence and humiliating acts. One victim is made to dance and the footage is then uploaded to the internet.
Sadly these groups are not uncommon and this treatment is far from rare.
In September last year, the BBC revealed more shocking treatment at the hands of the ultranationalist group.
In its footage, one man is forced to drink urine and put his head in the toilet before he has a metal bucket put over his head.
He is then whacked across the head with heavy truncheon like objects and is accused of being a paedophile.
The group say they are dishing out justice and their supposed aim is to cure people of homosexuality.
In the clip posted online, a woman can be seen armed with a gun and dressed in army fatigues, joking that she’s going hunting for gay people and paedophiles.
The woman, named as Yekaterina, heads up St Petersburg’s Occupy paedophilia movement and she tells the BBC exactly what the movement is about.
“Our priority is uncovering cases of pedophilia,” she says.
“But we’re also against the promotion of homosexuality. And if – along the way – we encounter people of non-traditional sexual orientation, we can kill two birds with one stone.”
Last year, South African student David Smith found himself the target of a shocking attack by anti-gay activists after being lured to an apartment in the city of Belgorod.
In the graphic online video, Anti-LGBT activists pretended to be a 15-year-old boy looking for sex.
But when Smith got to the apartment he was met by a group of men who subjected him to a humiliating experience.
He was stripped down to his underwear, asked if he wanted to have sex with a cat and had his head smashed into a watermelon.
Russia is renowned for its intolerance of gay people and last year introduced a draconian law which allowed police to arrest tourists and foreigners whom they suspect of being gay or lesbian.
Under President Vladimir Putin’s law, police can detain suspects for up to two weeks, with their powers even being extended towards people considered “pro-gay” or distributing “gay propaganda”.
This month, Russian MPs are set to debate a bill that could see homosexual couples lose custody of their children.
If passed, the bill would meant parents risk losing custody of their children if they practise “non-traditional sexual relations” or, in Russian terms, gay sex.
