<b>When the welcome bot backfires</b>

Automated welcome messages are near-universal. A subset of the evidence says they can suppress the very behavior they're meant to spark.

<b>What the data shows</b>
A few A/B tests shared by community-bot vendors found that long, link-heavy automated welcome DMs reduced first-post rates compared to a short human-style greeting in-channel — in one test by around 10–15%. Bot pings that demanded reading rules before chatting fared worst.

<b>Why it happens</b>
A wall-of-text bot DM signals 'bureaucracy ahead' and front-loads cost before the member has any reason to invest. A brief, visible, low-pressure greeting in a channel models the norm — short messages are welcome here — and gives a hook to reply to.

<b>Discord vs Telegram</b>
Telegram's join-message bots are even blunter, often firing a captcha plus rules wall. Effective for spam control, costly for warmth — a real trade-off, not a free win.

<b>The caveat</b>
These are small vendor tests with obvious incentives to sell 'better' onboarding flows. Replication is thin, and what counts as a 'good' welcome is culture-dependent.

Open question: can a bot ever model conversational warmth, or is the welcome the one job that should stay human?
