Yes, using so many unrelated outbond links may be a cause of banned by search engines
But that would be at the max 40 outbound links to a single Site like Facebook!
I got your point. See if all link are resources, whose image or content you are using, than you can add his link.
But if you just want to all outbound links, like you were been paid for links or got link exchange, on the page, where is not much good content, it may harm you. If you have good content on web page, you can add some outbound links. just like reciprocal link exchange.
In my opinion.
Articles with relatelink to external sites that have related content.
quality of the article seems to have increased even more.
Because they facilitate for the reader to get more news content. It was generous.
If I say that we have outbound links to lower ranking.
It sounds funny.
