Concerned with some of the language in the EU GDPR, I removed commenting from my WordPress site but retained Webmentions. A newer webmention spec allows for deletion and or modification of webmentions which I feel aligns with the GDPR. I considered using Disqus for commenting I am loath to outsource my comments to a silo. Isso may be a solution that allows me to retain control while also allow commenters control over their comments.
