Fedilab is a Fediverse client for (according to the website) Mastodon, Peertube, Pixelfed, Pleroma, GNU Social and Friendica. You can also follow kbin users (and, I assume lemmy ones as well, though I haven’t tried). The app will allow you to manage several accounts on Mastodon, Peertube and Pleroma instances.
You can block content by keywords or phrases (either hiding them with a warning or hiding them completely) but I don’t know if you can bulk upload keywords. (You can add several keywords/phrases at a time manually.)
Unfortunately (for you) the app is currently only available on Android.
You’re not the only one who’s picked up on this:

If you watch the show (and I’ve watched it a lot) you can tell that Aaron Sorkin wasn’t writing to a detailed plan. I think a lot of his ongoing storylines grew organically (and were often turned in very late, which ultimately led to him being sacked from the show), which meant he sometimes repeated, or retconned, beats, or made other mistakes.
Hartsfield’s Landing was probably named after Hart’s Location, another New Hampshire town that has often votes at midnight. I recall reading a story that, because of the weather, of the three towns that usually do vote at midnight only Dixville did so this year.
edit: Hrrm. Turns out that’s what the linked CNN story actually says. Serves me right for not RTFA.
