As far as the name change - here's the press release:

For reporting - while a report to ASACP is a good idea - for people that live in the US the law states that you have to report them elsewhere:
42 U.S.C. 13032 – REPORTING OF CHILD PORNOGRAPHY BY ELECTRONIC COMMUNICATION SERVICE PROVIDERS
Whoever, while providing an electronic communication service or a remote computing service to the public through a facility or means of interstate or foreign commerce, obtains knowledge of facts or circumstances from which a violation of certain offenses involving child pornography is apparent, must report those facts or circumstances to the [CyberTipline] at the National Center for Missing [&] Exploited Children as soon as is reasonably possible
Now - one of the things that ASACP does is to look at the content and report it to the NCMEC if they determine it to be true cp - that said - with the amount of people that use that type of text in an email to lure people in - in 90% of the cases it is not cp
If you look at the stuff to see - then report it immediately if it is, then "normally" you would be protected under the law. ASACP assumes that you have already looked at the material when you report it as just reporting something based on linking text isnt justification
