[I’ll edit this comment with a picture illustrating the process.]

While we wait for the picture, I will use an analogy to provide a mental one:

Imagine a family tree. That is the chain of trust, in this analogy. Ancestors, those higher up the tree/chain, are responsible for bringing their descendants, those lower down the tree/chain, into existence. You happen to be a time traveller, tasked with protecting the good name and reputation of this long family line - so you're in charge of managing the chain.

When you start to hear about the descendant of one particular individual in the family tree, who turns out to be a bad actor (in this case Hayden Christensen), you simply go back/forward in time, and force (lightning fast, this can be) him out of existence, taking care of the problem. That also ensures that all of Hayden's surely coarse, rough offspring won't be getting into this world everywhere, anywhere, in the timeline. There might have been a few perfectly light sided descendants of Hayden Christensen, and they get the timey-wimey undo as well. Too bad for them! Casualties of dealing in absolutes.

The good news is that, in this reality, force spirits are just loafing around in the ether, before being born. Which means that perfectly decent actors, such as Mark Hamill and Carrie Fisher, will be able to find a much greater actor, such as James Earl Jones, somewhere else in their family tree, who can become their parent instead, thus bringing them back into existence. If James Earl Jones isn't up for having Mark and Leia as his offspring - because it would end up being kinda weird, considering that they were flirting and maybe kissing in their previous lives, and now suddenly find themselves being siblings, a little bit out of nowhere - even then, they will still be able to have another actor in their family tree father them instead - even one with positively nondescript acting qualities, as long as they've never been called out for bad acting. David Prowse might become their Dad, for instance.

Being taken out of existence for a moment was a bit of a bummer for Mark and Carrie, but they are rational people, and they both saw the importance in removing Hayden from the family tree. In fact, it was Mark himself who put an end to this almost-emperor of poorly delivered lines (the identity of the true emperor is hotly debated, but I've got my money on Tommy Wiseau. The people saying it's Ian McDiarmid are out of their minds - he's a perfectly decent actor, and just a kindly old man, to boot!), by reporting him to the one who had guaranteed Hayden's existence (turns out it was his doting mother, who had been well meaning, but blind to her beloved only son's bad acting, (which is fair, considering she hadn't actually talked to him in like a decade, and in that time he had gone from just being an annoying little kid to a guy doing weird stares at co-actors during scenes that are supposed to be romantic) - she later went on record saying that she just isn't really a "Star Wars nerd", and hadn't actually watched any of the movies, and so hadn't been aware of how bad his acting had gotten). Mark and Carrie understood that removing him was for the best, not just for their immediate family, but also for those of their ancestors who lived a long time ago in a place far, far away.

Anyway, by Hayden's own account, "a hack[sic] calling himself ST4RK1LL3R^_^0rders^_~69 had gotten into my account, and 'made me do it'" (blackmail?), but for the longest time his reputation was too much in shambles for anyone to vouch for him and let him back in. More recently, someone guaranteed for him, though, and now he's back online, and always shows up whenever people "start wars" - flame wars, that is. Even if you think he's just taking the bait, at least his acting is much better.

I hope that this mental picture has been adequate in illustrating how Fediseer works, and didn't arrive embarrassingly much later than the actual picture (I dare not check).

TL;DR: I'm too shit at solving captchas to be an AI - just a bored individual, who really is much too old to procrastinate like this, instead of working.

Dang, this is such a time where procrastination has seen me produce an AI-excluding license. Siri, email this to myself, put CC as CC. How do I turn this off? Siri, stop
