Actually it's in honor of my brother's birthday because he actually was 13 when I started using the account name. (I am a few years younger) I didn't learn about the HH thing until many years later, but I keep it anyway because thinking about my brother makes me happy whenever I notice it.
What is with so many people on Lemmy suddenly deciding it's their job to police the internet? I haven't seen that behavior in months and I've suddenly seen it a lot just within the last week or so.
