You watch a person because you want to see their art and/or journals pop up in thee big List o Stuff on FA.

If you have any reason that you don't want their stuff to show up in that big list, you unwatch them. :)

As long as you don't go all drama "OMG, I'm unwatching you because of this thing!" style, you're fine. :) Don't feel bad,, don't apologize, don't drama. Just unwatch silently and go on with your life, watching the people you want to watch and not watching the people you don't want to watch.

On the topic of NC artwork: I'll really worry when somebody ties up an artist or something and forces them to art. :)

You can not like things if you want, and if this is how you need to deal with it, its proper, and alot better than making an ass of yourself.

That said, I think if someone on my list draws something I dont like, I can just over look it, and move on toward things by them I more approve of.
But thats just me, I only disapprove of a few things, and I have had to ignore alot of things I dont like in my life, its become somewhat of a second nature.

You have the right to judge all you want. We all do. If you don't like it, you don't like it. It doesn't matter why.
