"In the wake of this whirlwind of graft and plundering, anyone who wishes to set things right must have an organized ledger of all the things that have been made wrong." A subject, a note, the receipts. Yours, kept on your own PDS.
Heads up: your grudges are ordinary atproto records on your own public PDS repo — technically world-readable, like everything else you write to it (nothing here is end-to-end private). See the lexicon. Don't log anyone else's private information here — write about what happened and what you can already point to.
