Occasionally, an artist blocks me for adding their work to my favorites and collections. I don't know why anyone would block a potential fan other than not wanting more fans which seems illogical to me.
It cannot be that I commented something inappropriate or disrespectful because I always display the utmost respect. I do not always comment because I don't like to repeat what others have previously said.
When I have the opportunity to favorite images, I tend to 'fave' many at the same time.
I do not post my own works because I do not want critique i.e. shy, very critical.
