Use rel="nofollow" instead of hxxp
I've seen you are using some old technique for hiding links from bots like Google-Bot or Yahoo/Bing whatever. Instead using these hxxp things which are annoying for users you can say "Bots please dont follow this link" like this:
<a href="http://example.com" rel="nofollow">MyNoFollowLink</a>
Users will not see any difference and bots dont follow it. You should also add this by default for links from users (prevents spam on your site)

Thank you for your suggestion!
We will make sure to implement it, because it seems like good practice.However, crawlers are not the only reason we use hxxp - one of the main reasons are referers. We could attach some anonymizing service to all links, there are very few resources for that at the moment, though.
Additionally, many crawlers actually ignore nofollow.
