It's not ok to impugn someone's integrity just because of how something happens to look to you. The overwhelming majority of the time, these conclusions are wrong, it's the internet's fault for jumping to them, and they poison the community.
Real abuse exists, we do a lot to try to counteract it, and we crack down pretty hard when we find it. But there needs to be something objective to go on.
Edit: by the way, it occurs to me that one of the things you said ought to be publicly verifiable: "just look at the comment history on those accounts -- all inactive/active at around the same time". If so—which accounts? If you didn't simply make this up, it should be easy enough to point to which comments and accounts match this claim, from around the time you posted it. If I'm wrong, I'd be happy to admit the mistake and correct it.
There are also no "dark thoughts" or sinister plots at play here. I was simply replying to OP who posed the curious question about how this thread evolved so quickly, and I as the cat, got killed.
However, we should both know by now that "anti-abuse" and AI/Algos only get you so far, we still need human moderation, and that was what I was doing -- using my brain to see patterns xD
I don't know what you want me to prove here, I don't have the data, I don't have timeseries metadata of posts or IPs etc. -- but it shouldn't take a genius to pick out at least a dozen early comments that had no comment history for >30 days and then all decided to comment at the same time on the same thread. Couple that with a thread subject that didn't really have anything of value (read: promotional) and it's quick rise to the #2 spot -- the conclusion I came to was that it was being brigaded/spammed/seeded/call-it-what-you-want.
This was all that I was trying pointing out, sorry if wasn't appropriate.
What are you talking about? I just went through about half the accounts that have commented on here, and while a small handful do look suspicious, most are normal-looking accounts with over 100 rep. Maybe people are genuinely happy for the OP? Is that so hard to comprehend?
Isn't that not what we're talking about? Maybe you weren't around to see all the "Congrats" comments and now the thread looks more legit -- I believe we call that "seeding", what do you call it?
