I am in total agreement with the quid pro quo situation; ergo you pat my back and I'll rub yours. Years ago on a now defunct website I had one person that gushed over everything I posted; good or bad. It got to the point of embarrasment.

Unfortunately if someone posts a compliment it becomes nearly incumbent on the artist to visit the gallery of the poster and respond in kind. So where do you draw the line? There seems to be few sites that are in the middleground. 

Might add that is obvious for your work to be constantly ranked highly it must contain at least one half clad bimbo holding a weapon that most men would find difficult to wield. Where is the interest, the humor, the attention to detail that is the hallmark of real art? Why have the standards plummeted? I see little imagination or inventiveness that was the hallmark of Brycers in the days of the Carpinteria group, or for that matter much of society. Pity.
