Infinitron could you or DU/Tauntaun do some automated find-and-replace, changing ".postimg.org/" to ".postimg.cc/" (either site-wide, in case there are some other LPs using that site, or just in this thread)? The rest of the url stays the same.
DarkUnderlord Taluntain Broken links == pagerank penalty, right?
I doubt it, I'm sure there are (dozens of) thousands of broken links on any decently sized forum. I would assume that it's expected that the older the content, the more links will be broken. Actually, from what I've read recently, google pays little attention to older content at this point and only what's relatively new matters much. In any event, I think we had a list of stuff that needs to be mass replaced somewhere, could do this as well when doing the others.
