Should I redirect links to external sites on the forum?

Question

Search Engine Optimization

Is it worth it to redirect external links on the forum, that is, make a link of the type http://mysite.com/goto?http://outsite.com, which, when clicked, redirects to an external site? What are the pros and cons?

Answer 1

This is done in order to:
- Remove the active link to an external resource (possible through nofollow)
- Hide the referrer when following the link.
If none of this is necessary, then it is not worth doing.
