Thanks for bringing this topic up. Personally i do think some of the recent 'commentary' on images posted on IIS comes very close to bullying. I don't consider myself having a thin skin concerning my interpretation of what something should look like, and I always stress that i see this activity as Art. Unfortunately, some people seem to lie in wait for someone to post an image that does not conform to their interpretation of the "imaging standard model". Uninvited reprocessing is just plain rude and usually demeaning to the original artist. For these reasons I do not post any more images on IIS. I get plenty of 'Likes' from Astrobin and family and friends, that is approval enough for me.
If your intent is conformity to the group then you will get advice that takes you in that direction, but it's not for everyone.
