Frustated with downvote or plagiarism strike on my posts..!!

I have been posting facts as my blog post on steemit. To post facts on steemit i have to study, browse website ,whatsapp groups, telegram groups and sometimes i read books to collect information.
And when i post them an account named Hive account@steemcleaners always downvoted my post🙁🙁🙁🙁 for plagiarism. They told me to put source links in post but how the hell
i post source link of hard copy printed book.
how i post source link of information i just collected from various whatsapp and other social media groups.
That's very frustrating steemit. Steemit is a decentralized social media platform but still we are not free to post anything we want to post.
