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.
If you content is original;then there will be no need for this..
If you birthed and groomed your idea yourself(in your head); then there will be no need for this
If you didn't just read(cram/memorize) through Google Search in a bid to reply to comment or make a post; then there will be no need for this
If you do not spin a text in a bid to cheat the system;then there will be no need for this.
Once the idea is yours it's almost impossible to be tagged a plagiarist,no two individuals(highly unlikely),can come up with exactly the same ideas,
and if they do, it cannot be exactly alike,
and if it is it cannot be exactly in the same words.
