Filter content for anonymose users by IP - votingapi_views

My goal was to create a view that present to a user only content he never voted for.
To achieve that i have create a Filter: “VotingAPI percent vote user” -> “has not been voted by” -> “currently loged in user”, which works fine for registered users.

In order for it to work for anonymous users I have patched votingapi.module so it would record anonymous users ip's:

while ($vobj = db_fetch_object($result)) {

votingapi_change_vote($vobj, $vote->value);

$exists = TRUE;

I have also patched votingapi_views.inc so the filter checks the anonymous user ip before presenting content :

+ if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {

+ }

+ $joininfo['extra']['hostname'] = $hostname;

+ }

}

$tblnum = $query->add_table('votingapi_vote', false, 1, $joininfo);

The resault is that the filter treat all anonymous users as one and show only content that wasn't voted by any of the the anonymous users.

Any idea what's wrong?
