RE: Code Wars Python Challenge Walk Through - Array.diff

I was told to post moderately,yet all Hive-Twitter Engagement are gone on Hive platform, as if that was not enough. I kept quiet and now you kept on downvoting those ones I posted again. Is this what Hive blockchain is all about? Please stop the downvote trail, and yet you never upvoted me once at all since I joined Steemit 2years ago and now Hive, yet you kept on holding back rewards. Too bad for your administration. Yet I looked up to you as my mentor. See what my so called mentorship is all about.
