I've found an alternative plagiarism checker.

I checked this opening post in my usual checker, and it only detected a small percentage.

I then used a site that I haven't tried before - http://plagiarisma.net/
and I switched to checking with Google ( it provides a Bing alternative ), I removed the tick in the exact match box as well. It gave hits on almost 100% of the content, and it highlighted the extracted phrases.

Thanks for sharing the information.
I used to use https://searchenginereports.net/plagiarism-checker/ : it's very useful and help me many times find plagiarazed contents. When i tried to check the post you mentioned i got 7% to be plagiarazed. With http://plagiarisma.net/ it gave me 23% but it took too much time loading. I don't know how those services work or what techniques they use to exactly differentiate which is the best and which is the good but what i want to say here is that the proof of plagiarism could be proven in both of the two tested checkers; may be i should use the fastest one for a daily use.

Sorry for broken english
