We use Monsido/Acquia to monitor website accessibility including readability, broken links and potential spelling errors. The ESRI Hubsite team has done a really good job of making the Open Data template as compliant as possible. One of the big issues I face on every scan is broken links caused by the "Sign In" link on every item page. I have "disabled" the sign in link in the site setting but this only remove it from the header, HTML for the sign is just hidden in a side bar. I can manually ignore the link post-scan but ideally would like have the scanning application just ignore these, anyway a "nofollow" could be added?
