It moves faster than people expect
This is the part almost nobody knows. Financial sextortion — where someone threatens to release an image unless you pay — often plays out in hours, not weeks. NCMEC told Congress that it “uniquely targets teenage boys between the ages of 14 and 17” and is “often perpetrated very quickly, sometimes within hours,” with offenders sending dozens of messages in under an hour (Senate Judiciary Committee testimony, 2025).
In research cited by the Department of Justice, grooming began almost immediately in 85% of sextortion cases, and a quarter of victims were threatened during their very first contact with the offender (DOJ). Thorn's 2025 survey found that among young people who had knowingly shared an image, about one in six started getting threats within 24 hours (Thorn).
There is no long slow build you will notice. The tactic is speed and pressure, on purpose, so you do not have time to tell anyone.
These figures come from different organizations using different methods, so they should not be added together. The consistent finding across all of them is speed.
