The only real complaint was in the editor, it was confusing, when I first started, that I needed to pay close attention to which card I was editing.
I messed up a couple times before figuring out the up/down buttons and how that impacted editing what I was seeing.
I just went back through it and everything looks good, now if I just had more friends that wanted to brave the learning curve in the hive.
I dropped the link on my minds.com account, but that place is mostly dead, too.
I used to get 100+ views on a post, but now I am lucky to get 10.

Those come from opntr.ee.

That tracker doesn't seem to be loading now.

The editor complaint is the useful kind, so thank you for it. You should not have to work out which card you are editing. It should tell you. That is a gap rather than a preference, and it is the next thing I am fixing.
On the blocked scripts, you're right: they are all from opntr.ee. I checked again after you posted, and checked if Vercel's insights were toggled on (nope). A full page load asks opntr.ee for things and no other host at all. No analytics, no third parties, not even a font from Google. In theory, it should be like that in practice x)
Brave files blocked scripts under "trackers, ads, and more", and here the whole number is the "and more".
One thing worth knowing: an account page is rendered on the server. With every script blocked you should still see the page, links and bio and avatar included (right?). The JavaScript is there for the editor and the motion, not for reading somebody's page.
And thanks for dropping the link on minds anyway. Ten views from somebody who actually opened it beats a hundred scrolling past.
