You're welcome! It might have been that. We checked your latest submission earlier and it seems okay indeed.
Hello,
You should indeed have received an email in January 2020 saying that your Fanfarrón font was rejected due to kerning issues. I just checked it again, and while it's not possible for me to tell you what was going through my head at the time, I might have had the feeling that the kerning was a bit too irregular maybe? When you write its name this way, "Fanfarrón", there's this huge space between the "ó" and the "n". In uppercase, there's this huge space between the "R" and the "Ó" for example. For such a great/fancy design, it might have felt like a problem to me. It might also feel like nitpicking at this point, but as you said, it is a part of that human system we have built, and it has its advantages and its flaws.
By the way, there is a "Contact" link in the bottom right corner of every page

There is a "BUY IT" button on the page if you follow the link Akira1975 gave you.
Thank you, I've updated the link.

Vielen lieben Dank. Leider finde ich diese Schriftart hier nicht.
Wenn Sie mit „hier“ „auf Dafont“ meinen, können Sie es nicht auf Dafont finden. Sie können es von Google Fonts herunterladen.
The general consensus is that it is custom work.
I was assuming they're looking for "Oooohhh... On The TLC Tip" since it's the title of their topic.
It's not free per se but it is included in some Microsoft products like Office.
Ahah well it is quite similar, to be fair

No worries, I had to dig just a little deeper to make sure
