Thanks for the heads up, everyone-- I've taken care of all the logged reports and if there are more instances with users not yet reported, please use the help/ask question section, to send us links to the users here, and where they've stolen from. We can't act, if we aren't alerted, and DUP has no auto-plagiarism checker built into the website, so we have to rely on tip-offs .
We do send warning messages to those guilty of plagiarism, with the intent to offer them a chance to remove the stolen content themselves and behave , moving forward. If ignored or repeated, then we ban and possible remove their account if they are so cavalier to think the rules about theft, don't apply to them. We also remove what we can of plagiarized content, based on what reports we are given , links, etc.
Hope this helps to explain and thanks to all who are so vigilant in spotting things like this.
