I'm not entirely sure what this hack. Does it prevent members from viewing the forum on Link Anonymizer sites or..?

No this hack adds an Anonimyzer URL to all (external if set in Options) links, so that if a member clicks on a posted link, the linked site will not see your address as referrer.

dont u think this will mess up adsense? because google do wants to know were clicks are coming from for that site to get paid

i would like to know if this will anonymize google adsense outgoing links. if so then I will pass on this hack then. Great hack though

It will only work on links inside posts, so as long as your adsense is not inside the posts text, it will work. You can also set domains to exclude from anonymizing in the vB Options.

So, If the http://anonym.to? slow down or die then the links in my forum doesn't work ???

no, all forum links absolutly free from anonym.to. You can just OFF this plugin or choose another site (for example safeurl.de)

The Meta Refresh in this Hack isn't harmless: http://www.url-hijacking.com/index_en.html

Meta refresh is (afaik) the only way to hide the referer but produces an 302.

So, if you wouldn't potential harm the linked page: dont use it (until (e.g.) google fixes this issue - and that may take a while)

A possible solution is to exclude the links.php (wich contains the Meta refresh) in the robots.txt to prevent indexing by SEs.

i've found a similar hack in a german board with the same problem, so i searched here for an alternative ...

and now decided to give it up to hide the referer, cause i didn't see really why i have to.

PS: that's not a critic pointed to the hack, just an information pointed Meta refresh... ;)

I don't see what this got to do with this hack. URL Hijacking like described there is about links TO your site. What this hack does is nothing more then prefixing all OUTGOING links posted at your board with a configurable prefix. If this prefix is set to one of the sites that offer an anonymiser service it will just call that site. Standard vBulletin will anyway open external links in a new window, so i don't see what harm can be done. But ofcourse i don't know what each website that offer this service is doing.

Does this hack work correcly without any problem in vB 3.5.3 ?

Ihave not got any complaints about this hack not working for 3.5.3
