Buggy looking behaviour observed, when I view a post on another instance or make a post on another instance then go back to viewing it, in front of my eyes, I can see massive disparities in the amount of upvotes and downvotes. Talking a post showing 600 upvotes then a few seconds later, 5 upvotes, then 40 etc
Yeah this happened on some reddit clients as well it’s very interesting
On Reddit it was deliberate. That way bot users had a more difficult time to tell if their vote got counted (as they try to circumvent bot blocking and do vote brigading).
Here on Lemmy it’s probably just a bug due to high server load.
