Integrating the comment system to the blog is both an easy and difficult thing. There are some systems provide free plan like Disqus and CommentBox. To activate them only involves pasting a snippets.
GDPR Laws※
However, there exists laws on the user information collection. If I want to integrate the comment my my blog, it is inevitable that some user information will be collection unless I host one by myself. I don't want use some pop-up dialog to collect consent, since it can really annoy the user experience. Under GDPR laws, only essential information should be collected. For a comment, only email address is reasonable information to be collected.
I looked at CommentBox for a while. They claim they use no cookies and no tracking. This is the best option that I can integrate to my blog. But they didn't clearly state that they are GDPR compliant and they collect user names (probably okay) and user photo profiles from other social platforms. These information can be controversial as needed information. So I am not sure if I can safely integrate it to my blog.
Disqus stated that they are compliant with GDPR laws, however, a consent must be collected from the users.
Another Way of Collecting Consent※
After some search, I found a alternative solution to using a consent manager. I can use a delayed-load of Disqus so Disqus will only be loaded after the user clicked a “Load Comment” button.
As suggested by Google, I also need to put the Privacy Policy. I generated it from Google Gemini, which looks great (See it in Privacy).
Finished※
Now, adding a commenting function to the blog is finished. I didn't realize I needed to know this much about the GDPR. Same for website tracking (page views, etc), I use Umami since it complies with GDPR and without user tracking.
