The Tinder perverts who spend their time sending dirty messages to strangers drove one Los Angeles woman so crazy she decided to capture them on camera.

In 'Perv Catchers,' a video from comedy YouTube channel Super Deluxe, Jessie, 31, sets up a sting to meet the potty-fingered texters who send crude messages like 'You look like a good f***' on the dating app.

But what she finds - to her surprise, and probably the surprise of many other women - is that some of them are 'sweet dudes.'

Filthy: Jessie (pictured), 31, received filthy messages such as these on dating app Tinder - and set out to meet the men who sent them

Surprised: All of the men - whose faces were blanked out in the video (left) - were surprised, as they thought they were going on a date. Jessie (right) had to beg them to come back for a talk

Lonely and tired of waiting for her Mr Right to appear, Jessie had originally set up her Tinder account to find a life partner.

Instead she found a world of filth. 'Are you looking for a big d*** to play with?' asked one man. 'You look like a good f***!' said another. Others invited her to sit on their faces or wondered if she liked to be spanked.

Most people might just ignore the messages, but Jessie, fascinated, set up fake dates with all of them on the same night, setting up a video camera to record their responses.

Many of the men just turned around and left when they saw the camera crew - but three stuck around to chat.

First though, she gave them a little gentle teasing. A promise to make good on the 'doggy style' a man had asked for on Tinder - with Jessie climbing up on the table - left him recoiling in embarrassment.

And her offer to let one of the men spank her like he'd asked on Tinder left him choking: 'Are... are you serious?!'

But slowly, the guys start to open up. 'I think that online, it's like... it's all words, you know?' says Mr Doggy Style. 'I think in person it's a little different.'

He adds: 'I guess online you focus on what you want, more than what the other person wants, so you're just looking - is there someone who wants exactly what I want? And then "bam" - let's make it happen.'

Cheeky: Jessie started her interviews with some cheeky banter, including promising to take this man up on his offer to spank her - causing him to splutter 'Are you serious?'

Sweet: Jessie concluded that all the men were sweet - such as this guy, who she got to re-enact their embarrassing Tinder conversation in which he professed a love for 'doggy style' sex

Jessie then tested that theory by sitting down next to him and making him re-enact their conversation, leaving him audibly embarrassed.

But other guys are less charming. When she asks Mr Spanky - who she said seems like 'such a nice, gentle dude' - why he'd offer to slap her butt, he says his remarks were 'a compliment.'

'It just seemed like that was what you wanted,' he adds, saying other women on Tinder 'like it.'

And another man, who tries to charm Jessie on camera when they first meet by emphatically telling Jessie she's 'gorgeous,' agrees: 'That's what y'all looking for, is pervs. I don't want to be...'

It's a surprising night for Jessie, who says that all of the guy she interviewed were 'sweet,' and not quite the drooling sex fiends she'd expected.

'I feel like a lot of these guys talk this big pervy game,' she says, 'but meeting them tonight, they’re mostly just sweet dudes that are lonely and looking for love, too.

'I wish they'd brought that personality online instead of being pervy.'
