Critiques of art are a very sensitive things, mostly because every admin in every group wants peace between members. What does that actually mean?
There are only three options:
a) ignore the posted art if you don't like it
b) like it
c) comment, but only positive
Problem is that critique of art is identified with critique of author and, according to the rules of groups it is abuse of the author and, automatic blocking.
In other words - you can't tell anything negative without being sanctioned.
What is, according to this, the meaning of a comment or critique???
