There seems to be massive photo upvoting, on things that shouldn't be. i mainly deal with fictional characters and cartoons, not actors so I only speak for those. Images changed suddenly. Like fanart, or something that was recently added? First I noticed it was all 'reboot' images of characters so maybe I wondered if it was someone who was obsessed with making all profiles have new version pictures. But then random things like fanart or crappy screenshots would show up randomly as top voted. Is this a troll or is there some weird bot? I spent time fixing so many characters. I hope there's not bots changing pictures.
Random Picture Upvoting in a Weird Way?
Yeah, I've been noticing the same thing. In a few of my fandoms, some kid who joined recently (and I don't want to namedrop because I'm certain this is a kid and I don't want to to put an actual child on blast) has been spamming stolen fanart into the characters' image galleries and then spam-downvoting all the actual official stuff (and also, for a period of time, spammed fictional character photos into the image galleries for their actors and then spam downvoted ALL THE ACTUAL PICTURES OF THE ACTORS THEMSELVES until I yelled at them to knock it off, and I'm still trying to clean up the mess they made.)
IDK if this is what you were alluding to, but i also know from a friend of mine that in one of their fandoms, someone's been spamming images from an old, poorly-done movie over stuff from the original source or the more recent tv show, and then spam-downvoted everything else to get the movie stuff on top. IDK if it's a troll/bot so much as it's just some very stubborn children who really want their personal favorite photos on top (even if they really shouldn't be there in the first place..), but either way at least I know I'm not the only one noticing this.
I think I've had some encounter with someone that matches with the person you're referring to.
They were randomly voting on stuff and votes 'NO' on some of my things that I made on a friend's story, for no reason at all and didn't even make a counter suggestion.
Then I saw them again casting some character from their fandom on a story and then mass downvote the other suggestions so that their pick could come out on top.
Although I don't wanna make conclusions, bcuz this might be a different person from the one you're talking about.
It's hard to believe it's one person or one kid because it's in like every cartoon/animated fandom I see? A crappy Screencap or fanart gets upvoted. That's why I wonder if if it's a bot. It's just weird. Once I fix it it seems to stay usually so maybe the bot is done?
