Rewrite Link URLs in page

That would allow each user to tailor their own proxy/anonymizer link redirect service.

Related to this would be to have the ARFCOM server locally cache all externally linked images.  This would stop tracking/analytics for places like imgur and similar.  They'd load once a week or day, then be deleted/expire if that thread wasn't viewed in a week/day.   If thread is viewed again, the images could then be re-fetched and locally cached.    This would keep images alive here for a short time if they are changed on the source end, or go 404, in addition to blocking tracking.  However, the overhead is really high and not simple to create.

Having a global change like that for a forum of this size and activity would require an agreement/permission ($$$) For the redirect hide proxy service, which needs to be vetted to NOT be collecting it's own tracking information on users.   The free proxies and redirects pay for their bandwidth and servers by selling user information, though it's 'stripped of identifying info', google et all can de-anonymize data easily with correlation due to the sheer volume of things tracked these days.
