As far as I can see, Leofinance articles go automatically reblogged at Peakd (and I don't know where else) anyway. And vise versa, an article from Peakd goes automatically reblogged at Leofinance.
I understand what you mean, but from what I know of Mr. Matt Cutts's theories, so-called "duplicated content" is not an issue since a long time ago. Google just prioritizes the copy it indexed first, not penalizes others. However, my SEO knowledge is outdated for like five years at least, maybe something changed since then.
Anyway, I think I've found a trade-off solution.
And it would be good indeed if "the curators" make their say on that. I will probably make a post on that later, maybe it will get some response.
