The ads seem standard targeted googlead stuff to me. Everyone that google can identify gets personalized ads based on what google thinks your interests are.
I don't know what ad anyone else is seeing, google thinks I'm in the market for a honkin' big lawn tractor and some frilly cheap decor items...
"Horrific ads"? What kind of searches have you been doing?
OK, sorry, sorry, that was funny not mean I hope. Ads are highly annoying especially on mobile where they cover half the screen and cost you data, but that's how the internet runs. The only alternative is a small group of techy involved people doing it themselves out of passion, with maybe some hosting costs covered by donation.
A community can still exist within the business model, but only via ad revenue.
