Not at the moment, no. I recall reading it on another reddit and being sufficiently convinced, for what that is worth.
The mod of those subs is /u/IrlOurPresident, and the submissions are restricted to pretty much only that account. That is where to start to trace down the claim.
Just noticed it's L, like /Lrlourpresident (because the I account got banned).
And look at the submissions, and the vote count of submissions. I do not have the comments I read several weeks ago available, but in my many years on reddit, I have no doubt there is clear vote manipulation occurring.
That's what I looked for. You should have better evidence than a highly active user in a restricted access subreddit before making an assertion like that. Especially considering how wildly popular AOC is, I don't see any evidence of manipulation.
Your instinct to shit on a lack of evidence is blinding you to the nevertheless present strong circumstantial evidence of vote manipulation on the subs.
You make a specific assertion like that, you should have at least a shred of tangible evidence. Believe whatever conspiracies you want, but it's not my fault you can't back them up.
Do you have evidence of that?
