that is the grey area 230 creates. Companies like facebook argue that they are more like the printing press that makes the magazine and not the magazine publisher. The issue arises when they choose to sometimes police their content. But this would be true even of a printer if a long time client that sold cigarettes or something sent in ads to be printed targeting kids it seems reasonable they could refuse services. But where to draw the line as 230 says they are not responsible to do that so does that mean if they choose to enforce decency rules are they responsible to be watchdogged or must police all content?
