You are right. I don't mind the upvotes being public, I do mind the deletion thing (although it's an inherent flaw of federation, hard to get around it) but both are points against it having good privacy.
I guess what I meant is that the platform makes no attempt at linking your online persona to anything else. It doesn't even collect IP adresses and has very poor logging - btw this is actually a liability with the ongoing CSAM issue.
Oh thanks for that. Looking at the plugin's wordpress page I ended up on a wordpress SVN page and thought I had to browse that. My allergy is already much better, I might have a look after all.
