Yeah, the old Napster/Limewire days were rife with people labeling any kind of parody or meme song as being written by Weird Al or SoaD. Probably because they had the name recognition and would actually show up in search results. And it was just plausible enough that they might make a song like this.
Weird Al even went on the record to say that he absolutely hated the trend. Because a lot of the parody songs that were misattributed to him were very vulgar, and he historically avoided things like excess profanity so his music would be safe for kids.
Also, I’m amazed OCRemix is still around. Pretty sure half of the music on my original iPod Shuffle came from that site.

Just looked up some of the songs on my old playlists, and they were all tracks numbered in the mid/low hundreds. There are +4800 remixes now.
