I've seen this said before, actually. I agree, and I think some people will give me funny looks when they see me at cableporn (really neat cables) or something like that.
Make a tiktok with "apple" by charli xcx in the background, subway surfers footage in the corner, and make the camera move further away from the screen (whats screen recording?) at random points.
I wouldn't consider it a hack, as the protocol was actually made with these posts in mind. Public posts weren't the focus of activitypub.
I would consider it similar to email, should we abandon it (yes, but not because of this) just because a malicious email server started publishing all the emails it recieved?
AP is just email but social media.
b-but it has a blue checkmark!
