I haven't seen any political ads on here at any time. Right now I'm looking at an ad for a webhosting company (via Google ads) and Amazon ads for Canon lenses.
As far as I know, 3FC is only running ads by Google and Amazon. Google displays ads based on your browsing history. If you have visited any political websites recently, that might explain the ads.
I'll pass this on to IB and ask if their advertising department is rotating an other ad types that offer political ads. If so, I'm sure they won't mind filtering them out, especially since we have a strong 'no politics' policy.
Thanks for your information! I'm going to close this thread since it might invite political discussion, and there's really nothing more to add to this since I'm contacting TPTB
I'll update you when I learn more.
