Do you really think it's more likely that "big porn" has astroturfing accounts that go around and downvote people like you who claim it's a money-laundering campaign, rather than commenters unhappy that you have no sources to back up your claims?
But hey, nice job putting words in my mouth.
As for evidence, you also have bing and google. There’s no shortage of it.
On Hacker News, presenting speculative claims without evidence to back them is unpopular, yes. I have desire to put words in your mouth, but I felt that there wasn't all that many ways to interpret a downvoting ring and an exposé you say this points towards.
To respond to your additional edit: presenting your claims and telling me to search online for evidence to support it…is not helping your point, nor is it really what I meant when I asked for you to support your claims.
