Not scold (that is how we shape social behavior), but only note that Safe Harbor essentially grants the opposite of this (away from the potential default of "By transiting malware you are complicit and liable in the effect of the malware") so it'd have to be a finely-crafted law to have the desired effect without shutting down the ability to do both online advertising and online forums at all.

... which doesn't sound impossible. It's also entirely possible that the value of Section 230 has run its course and it should generally be remarkably curtailed (its intent was to make online forums and user-generated-content networks, of which ad networks are a kind, possible, but one could make the case that it has been demonstrated that operators of online forums have immense responsibility and need to be held accountable for more of the harms done via the online spaces they set up).
