We tried this with a subsection of mde, it was powefulbadboys which was a good group of guys who weren't polfags. It eventually got noticed and taken down just because the members are the same. That sub didn't even discuss mde it was more similar to a different offshoot called milliondollarbabies. We literally weren't allowed to make a sub with the same members. I delete reddit accounts a lot, but it's hard to know who you're letting into a super secret sub when it's all unknown account, thus the wrong people get in and just start reporting again.
