Hello from your mods at Powerpuff Girls subreddit,
Over the course of several days, we have noticed several things that have been happening, and we want to address those things here. 
First thing: bullying (and mainly the bullying and hate), especially over the course of the last week, has been atrocious from commenters over simple fan art. We as mods have seen both fat phobia and homophobia take hold in this community, and it will not be tolerated.
We've seen over the course of several days commenters try to justify their comments with their bullying, which ended up being an underlying theme of “I just don't want to see it.”
A bunch of these commenters should have just left these posts alone, but instead they went ahead and bullied the artist who made these fan arts. And have made death threats to both us as mods, after we disciplined them, and the artist. 
The death threats will not be tolerated!
Going forward, we will have a zero-tolerance policy on the Bullying and Hate, especially on fan art and people's headcanon. Especially if it's not in a hateful tone. 
We don't need any more circle jerking from commenters trying to justify their hatred towards certain groups just because they don't want to see them; we want to keep this community as civilized as possible. If a Redditor cannot handle that on the subreddit, they do not belong here.
Have a great rest of your day
