They still offer advertising only to cardholders from the US, Canada and the UK. I really need to advertise on Reddit for a Reddit related website.
Couldnt you get a US or UK resident to pay for you? You could reimburse the person with bitcoin.
Would if I could but it's not like there are agencies that you can easily find via your favorite search engine.
For now, yes. This is because outside of those countries the way you purchase an ad on reddit could be considered gambling. Once they switch to a pageview based system you'll be able to buy ads from lots of countries.
