What kind of sites are being censored? I still see links to sites that sell SAT Blue book answers, the online SAT course, ocassional links to useful material on the Kaplan and
PR sites. The "censorship" (if you call it that) has gotten a lot better over the years - mods used to delete absolutely any link anyone posted. I remember a while back (~3 yrs ago?) that links to a Congressional report on SAT scores vs. family income and race were removed for violating the terms of service, which caused a big debate at the time.
