I have an issue with this only because these types of groups end up excluding everything except a narrowly defined piece of work.
For instance I literally watched as one group went over time, from accepting a wide arrange of art to only accepting hand drawn portraits of celebrities because there was some confusion over what 'good' was among the moderators.
Now, I'm not saying my art is great on the contrary it's quite obvious that it is average, however I recently got into making sprites which are beads that you make pictures with and then iron.
I tried to submit one of these pieces to a group of this branch because it was a pretty dandy piece( the best of all I had made), but it is a less popular art form and I feel that it wasn't declined because it wasn't good but because it didn't fit their ideology of the "best artwork"
I feel overall that these types tend to be very exclusionary even if they don't start that way. It's nice to want to encourage people to improve by holding them to high standards but what about those artists who work really hard at something, get it exactly right and they're still told it's just not good enough because it's not a portrait or a landscape or a black and white photo but instead say, a statue made out of toilet paper?
But hey I'm just blowing off some steam, I already left the group because it's clear that it doesn't fit in with my current goals and why be a member if it doesn't benefit me anyway?
