I think it's a really hard problem. I guess I'm not sure what "rallying against certain kinds of sites" means in practice - encouraging regulation? Social media campaigns against those sites? It seems like bitcoin mining has proven resilient to regulation because as soon as one place regulates the miners slip away to somewhere else. Getting ~200 countries to collectively agree on a set of regulations in such a quickly shifting landscape seems near impossible.
As for social media campaigns, it might shame some people but not others.
I don't have much of an answer for what to do here besides "hey, if I want to do a crypto project, I'm going to choose a chain that I feel like is being ethical".
