Arrrgh mate... happens all the time to me... there are even peopel keeping spreadsheets of favs, comments, who favs, who comments.. and cycles the days to maintain a higher than would be expected rating for their images... it's called the hug club... and unless enter into the club and are accepted by them... that is fav and comment back... then your images will always be crap in their eyes. Small people with large egos and no artistic talent whatsoever... a bit like me really... but I rely on hopefully, some crativity in my images, not much I know.. but I try. We really don't need a rating system at all for artwork... the best rating system, is when someone buys your artwork, I really like that system.
