Doesn't look like a double post. Did you mean cross posting? And if so, why would they care? Surely their mods can't monitor the entire internet for cross-postings.

Yes cross posting.

Reddit/rperl has an explicit policy to tolerate cross postings.

I was criticized once when flagging a cross post involving perlmonks there.
