They did this stuff with proto-SD stuff back during Trump's first term. Whenever he posted something they'd flood his replies with very very stupid shock images. Stuff like an extremely ugly Trump wearing a befouled diaper.
It was a form of Gatekeeping, designed to make Trump supporters recoil and not want to engage in the space, or get them upset enough to tell the posters off (which would get them banned for hate speech). Posts were being made at the rate of hundreds if not thousands per second with this content, so it was literally impossible to deal with. And since Twiter insiders at the time allowed it, reporting it did nothing.
In other words, it's not about gooner stuff. It's about making people recoil when they think Elon/Trump, so they associate recoiling when they see Elon/Trump. It's one of the ways they program the NPCs to hate hate hate hate hate hate hate hate the people they want them to hate.
