I just opened my first ad on Steemit it because ad revenue only flows into Steemit if their referral is actually used (and because I am a curious primate who likes to click on new buttons).
What did I expect? I guess I had higher expectations for Steemit that for Google, Facebook, or other ad companies. When you start with ads in 2019 you have the opportunity to be more conscious about its effect.
Well, my first ad looks to me like a boring money scam (it is in German and you can safely ignore it anyways). Clearly the ad algol has not been briefed about the crypto-aware readership on Steemit.
