I´m afraid this is the result of the art-charts. So many users have begun to post stock-comments with copy and paste to each image that is showen as new in the gallery. When I have begun here, they where happy with 20 comments, but now they are in the need for 100 that they are showen in the top of "most commented images", and they are in the need for many new favorites to climb in the top of art-charts. 
So they are post about 200 comments dayly with the hope to get 50 back. 

For me, I don´t like to write the 85th comment under an image as I know, nobody will read it really.
