A few days ago Disqus released a featured called "Recommendations" [0]. I haven't received any email about it, and it's enabled by default. It inserts additional HTML on top of the comments, and when I first checked my site I thought that my site had been hacked or something, especially because one of the recommendation was for a different site altogether! [1] It's a Japanese site that I never heard of, does not have similar content to my site, and it's of course on a different domain, so why did Disqus think it was ok to include?I don't know why Disqus thought it was ok to add HTML and outbound links without even sending an email first. After this, I surely won't use Disqus anymore, and if there was a way to migrate without losing comments I would remove it from my site too.
To make sure recommendations are disabled for your site, go here:
