Hello.
Thank you for your support throughout the years..
We don't use tools to detect plagiarism. Online tools are more or less useless. We have been always investigating manually by use of different search engines.
Some investigations are hard to crack because a lot of plagiarized content is a transition from another language than the language in the post or content is spun/re-worded.
I sent you a message in Hive Blue.
I would be happy to explain to you how our investigations work with some examples if you are interested.
