Kuvaus
Locally mirrors commenters’ Gravatar, Libravatar and Mastodon avatars and serves them from your site, rather than loading them from a third-party web site upon each page load.
This has several effects:
-
If most of the comments on a post have no avatar, those turn into one load of a shared image, instead of one for each comment, that happens to return the same ”mystery” image.
-
You will be serving more (small) images.
-
If a commenter’s URL looks like a link to a Mastodon / ActivityPub profile, their Mastodon account’s avatar will be displayed.
-
When commenting, a live preview of the Gravatar tracks the contents of the ”Email” field.
-
gravatar.com and libravatar.org no longer have a web-bug on your blog that is loaded by each viewer. Instead of being loaded at every page view, the avatar is loaded just once, on the server-side, at the time each new comment is posted.
-
If someone changes or deletes their Gravatar, your site continues displaying the image that was their avatar at the time that they last posted.
-
Likewise, the user’s Gravatar profile is saved along with their comment, viewable by admins even if they later change or delete it.
Security and Privacy
-
Libravatar is open source. Gravatar is owned by WordPress, and their privacy policy says that they don’t monetize that info. But hey, corporate policies change, subpoenas exist, and domain names get sold.
-
Should you trust Gravatar with user data? Well, in 2024, Gravatar announced that they are pivoting to blockchain, whatever that means, so that’s fairly disqualifying. See also WordPress ”growth hacking” and WordPress sells users’ data to train AI tools.
-
There used to be a potential issue due to Gravatars using MD5 hashes, but these days they use SHA256, so I assume that’s no longer a problem.
