The positive point of REVAIN's community competitions is that the rewrited texts is not accepted. It is very important that the content on such platforms is original and copyrighted. It is logical, rewrite is not allowed.
What parameters will be used to check the uniqueness of the text? What percentage should be unique 100%?
Probably 100% unique. Look, in the terms of the competition it is written that rewrite is not allowed, please. I think that reviews should be as original as possible. How can it be difficult to write your impressions and Express your opinion? On REVAIN platform of freedom of speech, of course, within the rules and it's great.
