Yup. their ad targeting is context. super basic 'interests' and specific sub reddit placements. I haven't found it to be valuable.
I just looked to double check nothing changed since I last bought something and it looks like the have a customer match but only as a holdout/narrow. Which is weird if true? as in can't upload a list and target those users if i'm reading their page correctly
pushing their s*t redisign and mobile app on us with more feed ads might mean they are trying to push for 1st party data based targeting though
