Because most people are using YouTube or Discord or social media to debate, not this forum.
Forums like this are rather out of fashion.
...and that is the big shame of it.
Moderation on Discord, YouTube, Twitter etc is all but non-existent. It means CTs can spout their evidence-free shtick without limit, and without being held to any kind of standard. This is why I don't have Twitter or Instagram accounts (and I never will) and I only have a Facebook account to keep up with close friends and family. I have a Reddit account purely to follow r/spacex because of the high number of very knowledgeable people who post in the threads and because it is well moderated (space deniers and "rockets don't work in a vacuum" types are given the short shift at warp speed).
Folks here might be aware the Australian Government is considering a proposal to force the tech giants like Google and Facebook to pay for the news items they publish. Facebook's latest counter-threat is to propose to stop Australians from sharing news on Facebook and Instagram.
As this article quotes...
...Facebook doesn't ban fake news, it only tags it, but it is now saying it is prepared to ban actual news in order to tap out of a legislative process that is not going its way...

But the financial effect could be pretty devastating, on top of the walloping traditional media has copped in the last decade or so.
