Catering to an audience that engages in perpetuating falsehoods, fake news, and potentially hateful or violent content, is not likely a sustainable business plan. Without limits in place this will degrade quickly. I think that Google et al. see this coming and are trying to some extent get ahead of it.
Tomato, tomato (haha)...
See, I'm not "catering" to such an audience, so to speak; my demographic is localized, and I just happen to be in a politically extreme area.
What I realized long ago (and what I don't think that Google and Facebook realize) is that people believe what they believe, whether you let them talk about it or not. It's only with open and honest discussion that we can hope to change their minds. Which is why I believe it's better to let them say what they want, and let the other users reply and show them how they are wrong.
Of course, Facebook doesn't really care one way or the other, their ultimate goal is to monetize fake information like that (as per the 60 Minutes interview). But that's a whole other topic completely.
My point here, though, is that whether I'm right or wrong should be irrelevant. IMO, Google's job is to connect publishers with advertisers, not to dictate what can or cannot be published.
My sites are 20 years old now, and before Adsense I would make money on local business sponsorships at $1500 /each. The problem came along when a user said something the advertiser didn't like, and they would try to force me to moderate to their tastes. Example, the local Chick-fil-A decided that they didn't like someone selling vintage Playboys in my classifieds, so not only did they threaten to take off their ad if I allowed it, but they also threatened to lead a boycott by multiple businesses.
(Pure hypocrisy that they advertised in the local newspaper alongside ads for strip clubs, and used billboard companies that carried ads for strip clubs, but I digress)
I don't deal well with bullying, so I chose to lose them as an advertiser.
Adsense originally solved that problem for me; I was connected to a seeming infinite number of advertisers, and if one didn't like the content then they could move right along and make room for the next one that did like it!
In the last few years, though, being forced to remove ads from topics like hunting or dating makes me feel like I'm heading back to the same problem I used to have. I'm not being asked to kowtow to any individual advertisers, but now to the overseer of all of them.
Create a forum category for talking about topics that advertisers don't want their ads seen on then wall it off from Google and AdSense. When someone posts about it on the outside move it to the walled off category.
I've done that with other topics, but it worked out verrrry poorly! I have a main forum that gets the most attention, so when people are forced to post certain topics in forums with less attention they feel targeted. And to a large degree it's true! They can make a post in the appropriate forum and have no replies, then post the same thing in the main forum and get 20 replies in 15 minutes.
So it ends up being more work for me, less money for my efforts, and like tangor said: they still feel alienated.
Here's the messed up thing. With the whole anti-vax topic, they honestly believe that they're right and that they're saving lives! So by alienating them, in their minds, I'm the bad guy.
And we all know that small businesses are held to impossibly high standards. I'll lose even more traffic no matter what I do, and they'll move on over to Facebook; no matter that Facebook does the same thing, they're a big business so it's OK :-/
Gah, even I can't tell if I'm venting or whining... I have to stop posting these things at 1am, no wonder I can't sleep! LOL
