Working in a relatively small company in this space but offering services like smart contracts audits, we had a lot of issue to creates ad on multiple platforms such as AdWords, Reddit, etc. While our services were 100% legit and waiting for their approval I was bombarded with all kind of scammy ads that made me wonder if it is just that I don't know the right people at the company to move forward or my budget was so small...
BTW, we are organizing a developers Hackathon and the ad in X is pending for more than one day.
