Getting rid of cookies on our website - Wordpress, YouTube, AddThis, Google maps

The deadline for complying with the EU Cookie law is 26 May, which is just over a month away.

Rather than get permission to use cookies on our website which would either be intrusive or ignored we've decided to not use cookies. Here's what I've found as I work through the various things that use cookies.

Wordpress Comments

The built in wordpress comments feature sets cookies so that it can remember the commenters details for next time. I commented out (no pun intended) these three lines in wp-comments-post.php. (If you upgrade and this file gets changed you'll have to repeat this.)
// setcookie('comment_author_' . COOKIEHASH, $comment->comment_author, time() + $comment_cookie_lifetime, COOKIEPATH, COOKIE_DOMAIN);
// setcookie('comment_author_email_' . COOKIEHASH, $comment->comment_author_email, time() + $comment_cookie_lifetime, COOKIEPATH, COOKIE_DOMAIN);
// setcookie('comment_author_url_' . COOKIEHASH, esc_url($comment->comment_author_url), time() + $comment_cookie_lifetime, COOKIEPATH, COOKIE_DOMAIN);

Wordpress Jetpack Stats

The Wordpress jetpack plugin uses quantcast cookies (HT A. Cemal Eki). The wp-donnottrack plugin will stop this.

YouTube

When you get the YouTube embed code you can now tick the "low privacy" option. All this does is use the youtube-nocookie.com domain, so you could use that on existing iframe embed code. The SmartYoutube Wordpress plugin allows you to set an option so that this happens on all your embedded videos.

Addthis.com

For the addthis wordpress plugin go to the Advanced tab and put
{ data_use_cookies: false };
in the addthis_config values field. For an embedded button use this code:

<script type="text/javascript">
var addthis_config = { data_use_cookies: false };
</script>

This won't stop individual services, like twitter, using their own cookies, but it will stop the addthis.com cookies.

Google maps

For google maps use maps.googleapis.com rather than maps.google.com. HT barryhunter.
