Share of harvested posts flagged deleted. The spread is the headline: a model trained pooled across generals will partly just learn which general a post is in.
Share of posts with any slur, hostile imperative or profanity, per general.
Barely. Janitors are not mainly removing hostile language, which means toxicity features will not carry a triage model and the register labels really were the wrong target.
Domains shared across all generals — the clearest read on what the board is actually doing rather than what it argues about.
Most distinctive terms per general by log-odds against the rest of the board, so shared jargon cancels and only what separates them survives.
Positive:negative mention ratio per brand. Every brand on the board is net negative (all ratios below 1.0). A successful astroturf campaign produces a positivity skew; none exists here. The board's own shill-accusation rate is shown alongside and is under 3% everywhere.
Log-odds shift between the first and second half of the harvested window. Blue rising, red falling.
Posts by weekday and UTC hour across all generals. Sequential single-hue ramp, scaled from zero.
Deleted vs kept, on structural features only. Being an OP is by far the strongest single signal — 3.8x — which is why the triage model leans structural rather than lexical.
Share of posts carrying an image, and share phrased as a question. /sdg/ is three-quarters images; /sqt/ is the board's help desk.
Deletion rate for posts linking each domain, against a 1.36% board baseline. Commercial AI vendor and service links sit well above it — the closest thing to a promotion signal in the data.
Identical URLs posted many times. Most are general OP boilerplate — standing resource lists copy-pasted into every new thread — not advertising. Sample text is shown so the two can be told apart.
The <1m bucket is near-empty not because fast deletions are rare but
because the archiver never sees them. This is the truncation, measured.
From the complete 3-month index of 148 threads. Generals are 11% of all threads started on /g/.
Whole board, index only. Flat throughput — /g/ starts roughly a thousand threads a week.
OPs are removed at several times the rate of replies, consistent with duplicate and off-topic thread removal being a large share of janitor action.
Harvested posts, generals with ≥500 posts. This is what the model trains on.
