7 years ago actual script grabs a limited posts per feed. If you want to implement such a feature you need to rewrite all the mechanic of the script . You need also to consider if all socials API supports the infinite grabbing with "pagination". Some RSS feeds for example are limited and not let you grab more then X posts.
If you want to introduce a sort of pagination till the limit of post collected you can use other plugins like scrollers. Some users have spoke about it in some issues in the past
What's the best way for you to add an infinite scroll feature? Or a load more button at the end? Feeds need this to paginate.
