I just checked /r/linux, which I browse on occasion, and the three sponsored posts I saw on the front page were for Intel vPro, Adobe Creative Cloud, and Google Chromebooks. Those all seem at least reasonably relevant.
Really? I'd say they are closer to unreasonably irrelevant. Maybe I could stretch myself to see a Chomebook being interesting and relevant. To me seeing the other two would make me look negatively on the brands/products. If those who sees an add get nothing out of it except wasted time I'd say they are spam. Those sound like 100% spam to me in /r/linux.
Adobe and Chromebook ads are all over Reddit. I don't read any tech or design subreddits yet I get them all the time. I doubt what you're seeing is targetted at all.
