Four weeks ago I reported that Yahoo seems to finally have got a handle on the problem of criminals abusing its webhosting service for posting child pornography. Alas, the porn spammer only seem to have taken a vaccation. After those 4 weeks of almost no new child porn sites, they returned. I counted 36 new domains used for hosting child porn between December 12 and January 5.
To their credit, Yahoo have responded promptly to every single report I sent them and have shut down the sites, but it would be far perferable if they took measures to ensure they catch fraudulent registrations before the scammers have a chance to send spam and collect credit card signups from people who respond.
