Thanks Dear Hive account@captainklaus for the information. So, the answer at discord channel was: "All your accounts have been added to mack bot for mass spam with photo art theft and travel feed plagiarism". They are subjective and arbitrary, the photos are mine, they are not stolen, I have a huge file which some wanted to share here on steemit, learn from other users and grow in this ecosystem with my photographic project. They've ruined 1 year of work on this blog. I like the steemit project, at this point I stop the project. Thank you.
