God bless the internet - a place as cruel as it is creative.
Some young football fans in England have been given a taste of just what life is like when those in cyberspace decide you're going to be their next target.
A photo of five mates - all presumably West Ham United supporters - was uploaded to Twitter on the weekend before the Hammers played Everton.
English football has a long history of hooliganism and it seemed the boys in the photo were doing their best to intimidate any opposition supporters.
The caption on the photo read: "We'll be waiting for your boys tomorrow."
Four of the boys in the photo were holding instruments intended to do damage: a baseball bat, machete and a golf club. But one of them had nothing but empty hands, and that's when the internet took over.

The photo was reported to police, and has been retweeted more than 8500 times.
For the record, West Ham and Everton played out a 0-0 draw in a desperately poor Premier League encounter at the London Stadium.
It took 28 minutes for the first effort on goal and recalled Everton goalkeeper Maarten Stekelenburg saved comfortably from Havard Nordtveit's shot from outside the box.
Visiting manager Ronald Koeman made a double change at the break, introducing Gareth Barry and Ademola Lookman, and the tempo improved in the second period.
Lookman forced two opportunities in quick succession and put both wide, while Stekelenburg saved from Manuel Lanzini but there were few nervous moments for either side.
