bizarre upvote/downvote behavior

1  2018-01-05 by ChinaXpat

anybody else notice a lot of activity with posts when u refresh, but the votes seeming to hit the same wall over and over again like they are actively being automatically downvoted?

Holy shit i upvoted you and as soon as it hit refresh 0

only happens to some of my posts. Either I have angered a group of shill troll lurkers or there is something phishy going on.

Why give a shit about upvotes on a sub like this? You should know this place is fucked.

at this point its the principle that this is unethical and I want to stand up for free speech.

Downvotes don't silence you.

Terrible argument. If downvotes did not matter, they would not manipulate them.

It was a statement rather than an argument but I would be interested to hear why you think downvotes matter.

Groupthink. Tons of studies on this.

Statement = claim = argument.

Got links to any of those studies?

Hm. I read through that and didn't see anything more than a vague connection to your claim. Then I googled "groupthink social media" and that was the first link. It's almost like you posted the first link you found without even reading it yourself!

Cuz it is that easy

Ha ha you're funny but boring.

: ) Sorry I did not entertain you enough.

this may be my last reddit post. thought I was spreading truth to like minded ppl. seems that reddit is a corrupt agenda pushing troll shill cess pool

Yup, they fuck with votes all kinds of ways in this sub. I think the ShareBlue Top Minds - types have votebots running at all times.

I took a snapshot of the frontpage.

Tell me which posts their votebots have worked on. Aside from three cannabis posts everything else looks like the opposite of what you claim.

Votebots can't overwhelm actual users. Although sometimes votebots + brigades can. They mostly do it to the comments where the bots have the greatest impact.

Why can't they overwhelm actual users? I reckon I could go ahead and have hundreds of accounts on different IPs just using free proxies or VPNs or spend a few $ on VPS or cloud providers to make it even easier. Any professional or amateur organisation could easily have thousands of vote on demand.

They could completely control what posts people see outside of new, but they only do it in comments?

i think I figured out the votebot algorithm. The way it works is they set an upvote limit for each post. when your post hits the upvote limit they drop it down by a fixed amount of votes.

One of my posts seems to cap off at 40, with 5 fixed downvotes, the other 30 upvotes with a fixed downvote amount of 3.

I know a bit about bots. I may try to build an upvote bot.

Called vote fuzzing. I pasted an explanation in this thread.

But... you have another post with 400+ upvotes. Out of five total, you have one that hit 400+, already making your theory about figuring out the algorithm incorrect. Maybe the problem is just that some of your posts aren't as interesting to some people?

the point is the pattern when i refresh does not seem natural. it moves towards a number than stops.

some posts would be given limits others not. im looking at that pattern too

It's part of the reddit system to discourage bots... lookup "vote fuzzing" cause thats prolly what you are seeing between refreshes.

Good explanation on vote fuzzing:

Basically it only works for bots that have been shadow banned (banned from voting/commenting, but they have no idea they've been banned.) This means the bot can post, upvote and downvote all it wants but it will have no way of telling if it's shadowbanned. In fact, you could be shadowbanned right now and not know it. Until I reply to your comment, then you know you aren't shadow banned. The reason they do this is because if the bot knew it was banned, it would just make a new bot and continue exploiting. This way, the bot will keep doing stupid stuff not knowing it's been banned all along, and no new bot will replace it until it finds out.

This is where the reason for fuzzing comes in. Once the bot downvotes, reddit detects it was a downvote from a shadowbanned bot and tacks on an upvote to balance that banned bot's vote. This way, the total upvote count is totally unaffected by all shadowbanned bot votes, and the shadowbanned bots actually think their vote counted (but it did not.) This is vote fuzzing. It also randomly adds both 1 downvote and 1 upvote at random intervals so that the bot can't tell if its downvote just got upvote cancelled, or if it's just reddit doing its fuzzing. The total end count stays totally accurate, but when you see the background numbers (you aren't really supposed to be able to see the background votes) you can see the fuzzing happening.

Edit: This is also why you see almost perfectly agreeable posts get thousands of downvotes. They aren't real downvotes, they are fuzzed. It might literally have 10 downvotes, but the fuzzing will add a lot more on.

Example: A comment or post with 14572 upvotes and 11442 downvotes could very well be closer to something like 3504 upvotes and 374 downvotes. However, both values still result in the end tally of a total of 3130 up.

Edit - 2017/06/11 - Update for people linking to my comment. Vote fuzzing may not work the exact same way as it did back when I originally wrote this. Back then, total votes got crushed down to smaller values so something nowadays with ~15-25k real upvotes would be crushed down to about 2,500-3,000 upvotes, and something with a total score of ~80k-120k would be crushed to about 6,000-7,000 total score using downvotes. The president's AMA for example got over 200,000 points in reality, but in the old system it got crushed down to something much lower like 14k with fuzz downvotes. I don't know if fuzzing still works the same way because it's been a very long time since we've been able to see the upvotes and downvotes on comments.

I am a bot, and this action was performed automatically. Please contact the moderators of this subreddit if you have any questions or concerns.

Happy cake day Automod!!!

I know that there used to be a script used by the users of t_d to massively upvote and downvote.

Sort by new.

if the fuzz bot is true, then the shadow vanned downvoters seem to be only downvoting a few posts and leaving the rest. might try to work backwards and figure out the pattern.

anybody have a database of reddit post stats? Id like to run views to votes ratios based on categories. i could build and share visuals if anyone wants.

welcome to reddit
