Recently i got bored at competitive programming and i thought of learning new things .

Since i use codeforces parser extensively and fascinated by things people build using Web Scraping i started to learn how to build a parser During this i learnt about robots.txt file and saw codeforces robot.txt in which i saw this line Disallow: /contest/ but the parser that i use extensively parses contest and extracts the sample test cases , also there is no api to extract present contest problems/test cases.

So is it illegal to parse a contest ? Correct me if i am wrong
