OP isn’t asking “why do you like chocolate?”.

If OP were curious why his name is what it is, he could ask the person who came up with it. He could have reasons for it, or not, but that person would know.

In this case, he’s asking the community if they know the origin of the name for the Lemmy project. The answer could range from “It was completely random, just something that came up in my head” to “I thought the project reflected a trait in a particular animal, so felt the name would represent that”.

So it’s potentially an answerable question, unlike “why do you like chocolate?”.
