This really sucks. It is stealing from unsuspecting people, and if news like this were to go mainstream it could harm the overall reputation of Gridcoin which is still fragile based on how small the community is still right now.
Is there anyway that Gridcoin could ban running a certain version of Boinc? I suspect that many miners of Gridcoin are running newer versions as such it would affect very few legit miners by banning the use of the version.
