Depends on what your goal is. .social has half a million active users every month, so it certainly had some impact

Given that bluesky was hit a few days ago, could be a threat actor gauging the defenses/responses of 2nd tier targets. I wouldn't put it past musk to use ddos to generate bad press for non-x socials either.

Plenty of ways this could be worth someone's resources even if complete take down isn't on the table.
