Before you post, comments, tutorials, and answering questions you can check your sentence first on the engine that I used. I know many of users of bitcointalk know this and used for seeking the plagiarized post.
Double check your sentence before posting on any thread for your assurance, and not accuse as a plagiarist.
you don't need to do that if it is your own thought and written by yourself
I'm pretty sure you will never be accused of plagiarism if you write in your own words
if you need additional info in your post you can quote or make a reference to the source
The best way to prevent accuse as a plagiarist is by writing your own, original content, and not copy-paste any other's.
I definitely agree with this statement. As long as it was your own, there is no need to be checking sentences as suggested by OP.
People may have similar ideas but each can still be expressed or written differently.
true... write in your own words!
if you copy paste, make sure wrap it with quote tags or provide a link reference
