What changed

A burst of 23 posts in 40 minutes promoting a cryptocurrency giveaway, written in a tone that does not match this account's history. Several posts include shortened links not previously used by this profile.

Why it was flagged

  • Sudden flood of posts

    23 posts in 40 minutes — usual rate is 2–3 per day.

  • Off-brand financial content

    Repeated crypto giveaway language never seen in 18 months of posting history.

  • Unusual language patterns

    Sentence structure and emoji usage differ sharply from the account's baseline style.

  • Odd hours

    Posts went out between 02:47–03:12 UTC; this account is normally active 08:00–19:00.

  • New shortened links

    Links redirect through a domain first seen today, flagged by two threat feeds.
