Trolls and the like

[stock2007]

Ok I may be breaking a rule somewhere talking about this, but I'm sitting here waiting for it to stop raining...anyway over on FF and most other sites I as a rule only read Shenny stories as really that's all I like but why do so called 'trolls' review a story just to slag it off if you don't like it don't read it. There is one troll who posts the same vile review for every story...why? Do they get a kick out of it or what?
Sorry I know this site is not here for me to rant on but its safer here I once did it on a open site and you would not believe some of the things I was called
