Please consider marking user "craigrant" similarly, as one of his videos that I watched yesterday convinced me to take this investment, and make this post. Thanks again.
From discussion with another steemit user, it seems that perhaps your bot only scans for text -- it does not seem to scan the YouTube video that craigrant had posted a link to. So, you might want to either increase the manual effort of determining whether a video is in violation; or, look into speech-to-text software to assist in automating this task.
Again, thanks for your efforts!
