I typically keep to myself and I don't call out the behavior of other artists. However, this was cringy enough that I wanted to share a particularly toxic mindset with all of you, to be mindful of and watch for.

There is an artist on both DeviantArt and FurAffinity who you may be familiar with. Their art is cute and usually bubbly; a very sketchy and rough style.

This artist also posts journals, updates, chat posts, etc., almost daily, or multiple times a day, asking why they aren't receiving more attention, followers, favorites, comments, and advertising all of their posting platforms. At first, it came off as looking for attention and validation, the usual you'll see from time to time from beginning artists trying to find their niche in a crowded market.
But it continued... daily... often.

A recent post was, again, complaining that they were only receiving 'x' amount of favorites per hour and demanded to know if their watchers were dead. There were a few typical praise and attention comments, but one in particular stood out. The comment wasn't hostile in any manner and simply stated that 'x' amount of favorites per hour was pretty good, making the artist come off as ungrateful for the support they garner.
I likewise wanted to give input, having felt under appreciated before and eventually growing up and maturing to realize that art shouldn't be about attention and validation. When I clicked reply, nothing happened. This is due to the fact the artist deleted the comment provided by that watcher, which I had been replying to.
Instantly after deleting this comment, the initial artist made the statement that, in essence, if you did not outright praise and give affection toward her artwork, offering any kind of conflicting opinion, you would be deleted and banned.

"People who think 'x' is enough and unpopularity what small artist are deserve - f.ck off from my page.
People who think I have to be positive and love someone without reson and care about people who doesn't care about me - f.ck off from my page.
People who teach me how I have to live and what emotion I have to feel - f.ck off from my page.
Comments like this will be deleted, persons will be banned for forever.
Other who support, fave and share my art - welcome, thank you, you amazing. "

Wow... rough mindset. It's unfortunate that someone's immaturity and hostility prevents them from seeing any advice as anything other than a personal attack.

Regardless, I offered the following response.
" As cute and bubbly as your work is, the constant bombardment asking for more watches and favorites, or complaining about not receiving as many as you want, is not only depreciating the followers you already have and devaluing them, it's going to drive those same followers away. It can be a definite bummer when we don't feel our efforts are noticed, but you should stand back from time to time and gain perspective. Let your work speak for itself and drive your efforts for self improvement and fulfillment. Creating artwork should be for satisfaction of personal growth, fun, and exploration. Creating out of a drive for attention is not sustainable.
If your work is aesthetically desirable, it will draw attention and affection on its own. Let your work speak for itself.
Granted, because this comment isn't outright offering praise, I'm anticipating it being deleted, which will only devalue another watcher who enjoys seeing what you post."

To no one's surprise, and only proving my point, the artist instantly deleted my comment and banned me from their profile.

I haven't seen this behavior in a while, but it's unfortunate how entitled and, for lack of a better word, bratty, some younger artists are. You are not entitled to watchers. You are not entitled to favorites, comments, or being showered in praise. I used to feel this way and, thankfully, grew up to realize that art was for my own satisfaction. If it drew a favorite, it was appreciated. If someone took the time to leave a comment, even one not providing critique, I appreciated it.
Creating art for my own happiness is what paid off. I'm not the most successful or popular artist out there, and I'm okay with that.

Gain perspective. I have people who enjoy my work and it's warming, but I make it for myself. I have several amazing and loyal watchers and clients whom I adore. It makes me joyful to no end that they want a piece of art made by me.
I don't always receive a million favorites or comments to things I post. I'm okay with that.

In the end, please find perspective, to all budding and developed artists out there, that venting about a lack of watchers you perceive you're entitled to, will only drive away those who enjoy your work. It's unfortunate that an artist would block a watcher, after complaining about not receiving attention. It's a self-destructive and hostile mindset that is cringe-worthy all around.

Love what you do for you. Keep drawing, and take time to appreciate your progress and self achievements. That will give you more satisfaction than a favorite ever could.
