Banned for voting the wrong way

I wrote the script. You opened a post in a community and downvoted every comment. That's what the message is telling you
That means you really don't like the community, fair enough.
- I don't want to give OP the benefit of the doubt here due to their behaviour in this thread, but I'll ask more for my own curiosity:
  Is there a possibility of false positives if you happened to downvote everything from a certain community while browsing c/all, or is there a temporal element as well that'd make that sort of false positive very unlikely?
  
  I'm not a great programmer,
  This ban message only happens when someone downvotes a post then opens the post and downvotes all the comments.
  Is there a bug? Sure, lots! I haven't double checked the logs against this user yet. After work
  Notice the one thing this user didnt ask for - to get unbanned so they could contribute to any of those communities
  downvote everything from a certain community while browsing c/all
  If somebody consistently does that, they are not having a great Lemmy experience and they should block the community
  Does it do any good for all the atheists to down vote every catholic post? Nobody is benefiting from that behavior
- what community? I have no fuckin idea what you are talking about. If I downvoted a bunch of comments, it's because I legitimately disagreed with them and considered them not constructive. I have never in my fucking life opened a fucking post to down vote everyone in the comments. madness.
  If you made the script, the script is fucking broken. Absolute drivel, and absolutely power tripping bastards.

Couldn't happen to you on Hexbear.
- that is the silver lining of hexbear, and the reason I still appreciate the instance, even if the userbase are a bunch of edgelords (not all, but most). Also very funny you came here to make a meta joke about something not related to this thread, I appreciate the effort<3 love you buddy, I hope you are having a great day :D
- To be fair - Hexbear has blocked a community I moderate... So that bear still has claws.
  
  Yea, but you can't downvote on Hexbear, so you can't get banned for it :D

These posts are very difficulty to evaluate, because it could be that the mods are paranoid, and reading the votes wrong, or the bans are legit and you're just lying about it. 🤷
- check my modlog and comment history, I've never been on those communities. And since when was voting a bannable offense? One worthy of bans from multiple communities, but only on a single instance? This is your community, what is it for if not this? And what could I possibly be lying about?
  It's one thing to be sceptical, it's another thing entirely to be wilfully credulous.
  
  You got instance banned, this is how this is displayed on the modlog. You also seem awfully upset about someone saying there's no way to tell if you're lying. You need to chill a bit.
  Also Not being in those comms won't prevent you from downvoting everything in them.
  Finally I didn't tell you not to post, nor did I speak as a mod. I just expressed my personal opinion. Your reaction to it however is quite the escalation.
  Ps: our instance recently also voted to sanction downvote trolls. So yes, absolutely, some types of voting can get admin attention.

YDI, what did you expect from going there and downvoting all or even most of the contend there? You are aware that mass-downvoting is considered an act of aggression against communities, as it's literally an attempt to downrank their content in the feeds. Many instance admins also don't take kindly to this either, which is probably why they instance banned you from there. This instance that YPTB is hosted on is literally voting for a rule change banning brigading, and many more in the future will likely follow.
If you dislike all of a community's content, you should use the function to block communities. If you believe it is against the rules you should report it by reaching out to admins. Spamming downvotes won't help in either case, it won't make you stop seeing it, and it won't address problematic or rule-breaking content. It just makes you seem like a bot or a troll.
- I did not mass downvote, idiot, read the fucking post.
  
  So if I ask an admin to look through your account's DB voting history it wouldn't show a ton of downvotes directed at some Dubvee community, right? I mean you can say yeah but you can't exactly prove that. And I've found that people banned for downvote brigading argue that they weren't doing it because they're still under the impression mods and admins can't see votes. Which we can, and have been for a long time.

YDI. Mass downvoting is toxic.
- ah, so you cant read, easy to ignore, thanks.
  
  You are very welcome.

no idea who these guys are, but I've not been systematically downvoting anyone.
edit:
ironic :D
all seem to be dubvee.org, is this a potential federation issue?
edit 2: also trans rights, BLM, free Palestine, Ukraine is a sovereign nation, bigotry is wrong. just to be clear, I see a lot of people complaining about being banned and their shitty rhetoric reveals them. I try to be an ally, these bans are not warranted, likely a butthurt right winger.
- A bot was likely involved somewhere in the process (and with tons of potential for false positives), possibly even if it picked up something outside of dubvee. Though that is not the automated message (and I suspect they'd stand behind it even if it were a low amount of votes).
  Not sure if it's what you meant, but some of the bans like this stop all of activity from being visible to dubvee users.
  
  Gonna be honest, whether it's a bot or not, the idea of banning people for voting on posts or comments in some way you don't like is deeply funny to me.
  "YOU'RE INFLUENCING THE MADE-UP INTERNET POINTS THAT DON'T MATTER! EEEEEEK!"
  even I'm not so terminally online.
  
  Sounds like someone being careless with their authority to me :D

I am also banned from a ton of dubvee communities for some reason.

Unlikely, but are you using an unusual app? Maybe there's a gesture that is triggering down votes when you're navigating?
- I use vivaldi on my desktop and summit on my phone (great app btw, give it a go if you havent :) )
  
  I'm on Voyager at the moment. Vivaldi is better?
