The tweet splitter isn't all that great, but I'll leave it up if you want to copypaste the split tweets manually. Thanks for the suggestion!
Changes in the Twitter Developer API pricing make it impossible to continue running TwittRP without turning it into a paid service, which is categorically opposed to making RP more accessible to people — the entire reason I built the service to begin with. Given the questionable decisions at Twitter since the takeover, this was always coming but it's still a sad day.
I’m working on something of a successor to TwittRP for Mastodon/ActivityPub, with Discord integration. When and if there's something to announce on that, I’ll do so both on @TweetiePieHelps and my personal. If you're a developer interested in collaborating on that, please get in touch!
Thank you all for making Twitter RP awesome over the years. —Auska
P.S. Fuck you, Elon.
