I'm surprised so many are surprised by this....forums whether they are sports or motor orientated thrive on discussing bad experiences i.e. fings going wrong with their teams or faults occurring with their vehicles.
Sure there is some exchange over the positive aspects but nowhere near that which follows the negative events....human nature innit.
People use the Internet to vent and get away from their frustrations in life, in reality the vast majority of shit people say on here us actually true, they're just looking for a reaction.
