Minnowbooster is a very strange setup:

I was for no apparant reason blacklisted as well, and I contacted them on discord.

They said that my content was not of good quality/ not enough text ( I am a graphic artist ) and that I was violating their rules by posting links to my art on amazon.

In a very insulting way they did not take my questions seriously: It is like THEY want to be the people who decide what is good content and what is bad content.

For more then 40 years I take myself serious as an artist and good quality content provider, but these people know better.

I am glad that they are not "the owners" of steemit!

I stopped immediately with these strange and insulting types, then I just wanted to say goodbye when they threw me of the discord channel!

I quit Minnowbooster altogether instantly; I want nothing to do with them ever!!

By the way, I wonder if they ever check what kind of quality their automatic upvote engine is upvoting?
