After reading this post here I took a deep dive into the database and ran a few queries to see if I could use it to detect some basic manipulation such as brigading or other types of persistent hostile behavior.
I'd describe this as people who could have blocked a certain community but instead seemingly dedicate themselves to continuously downvote posts, maybe because they don't like furry stuff in general.
Each line in the image corresponds to one person and how many times they have downvoted posts in a given community.
I won't take any actions right now, this is all very experimental. I just wanted to share this with y'all to let you know that we admins have tools to give us clues about whether some sort of brigading is going on.
Interesting stuff. Personally, I'd urge people who don't like furry stuff to just block a community and carry on. There's nothing to be gained by obsessing yourself with stuff you don't like.
Furry stuff is cute. Why would 99% of people dislike it? I'm not gonna join furry communities because I'm not a furry, but I'd probably upvote furry content if it appeared on all and I'd think it would be sad to keep it off there.
To be fair in the context of the main topic here, it looks like all the communities being down voted are porn. Not quite the same as seeing a beloved furry character from a hit movie if they are engaged in lewd behaviour.
But they can always block them and forget about it than go looking specifically for it and down voting it.
Such is censored generally, so they have to go out of their way to see such.
Also don't get why people would have a problem with seeing such unless it was like gore, but I acknowledge that often people do have a problem with such.
Yours is not a common opinion, but that's beside the point.
The issue here is a combination of end users not using the block functionality, and a major flaw in how it's implemented (you have to visit that which you want to block.)
You're never going to change end users' behavior, so the beatings will continue until blocking functionality improves.
