Yeah, I notice at least by default on at least the Mailman 3 hyperkitty archive, it "leaks" information to gravatar.com using per-member URLs for images from gravatar.com ... ugh.
Yeah, looks like I'm not the first to notice this: https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/H...
Anyway, one more item to add to migration checklist of things to do, and from the above, looks like it's probably not too difficult to manage to do.

Mailman 2 --> Mailman 3 ... largely (but not entirely) done; holler if one notes any issues.

There were some glitches, notably with import21 ... and did find a work-around(/fix?) for that, and also had some issues with archive import+indexing, but seem to have made it past all that now (though still have some more validation checks to do, etc.).
And note that thus far, the merging of archive from the (temporary) balug-test3(a)lists.balug.org to balug-test(a)lists.balug.org is still pending. In the meantime, those archives are available here: https://lists.balug.org/mailman3/hyperkitty/list/balug-test3@lists.balug.... And the balug-test3(a)lists.balug.org is also mostly locked down to prevent changes (no new postings or subscription/membership changes).
