I have posted a question on Math.SE and spent a lot of time improving it as it has been on hold.
However an earlier inferior version of my question has appeared on a website called queryxchange.com. I am not going to post a link this must be happening to others as well.
I have never signed in to such a website and my name on the website is not a link to a user login page, but is just a link to the ripped off web page itself. Therefore the web page has not been created by a user claiming my identity, but is a copy created directly by the operators of the website.
I assume that math.SE does not condone this practice, which appears to me to be blatant copyright infringement. What can be done to stop this website ripping questions from Math.SE without the users permission?
