Many researchers are aware of ResearchGate, a social networking site for researchers. ResearchGate allows researchers to chat, ask and answer questions, and upload full text versions of their work.
Shockingly, a recent study has found that a huge proportion of the papers uploaded to the site infringe copyright. In a random sample of 500 English language articles, 108 were open access (published in an open access journal or had an article processing charge paid to make the published version of the article open access). Of the remaining 392 articles 51.3% infringed copyright and were non-compliant with publisher policy.
