To add on what Luca said—so far we have been indeed using similar content for the two Instagram pages that we manage, solely because the posts are written in different languages (English and Italian), hence there is little overlap amongst the audiences. Whilst we could indeed use similar content for a future page in Spanish, this would not be the case if other EA pages in English were to be created. I hope this helps!
