Unfortunately, freelancewriter, only a handful follow the one strike plagiarism policy
Is there anyway to figure that out?

Also regarding turnitin, I heard they keep a copy of your paper? Is that true?
Someone answer me pleeeeese this is what I found:
Under their terms and conditions they state:
License to Use Papers Submitted. With regard to papers submitted to the Site, You hereby grant iParadigms a non-exclusive, royalty-free, perpetual, world-wide, irrevocable license to reproduce, transmit, display, disclose, archive and otherwise use in connection with the Services any paper You submit to the Site. Please note that papers submitted to the Site are not read or reviewed by any individuals, but rather are only analyzed using the Service.Then under the FAQ's they say:
Does WriteCheck add my paper to the Turnitin databases?No WriteCheck does not add your paper to Turnitin's databases. Therefore if your instructor submits your paper to Turnitin, it will be seen by Turnitin as an original paper.
Isn't that contradicting??
Help!!
The only way this is reconcilable is if:
1) There is a turnitin database
This is where they store all the essays that are checked by lecturers and institutions
2) Writecheck
When students check their work using this service, then as they say, they do not store it in this database hence when the lecturer checks it, it will come up original.
Am I making sense?
