Why is there an extreme amount of censoring in Jojo (Stardust Crusaders) on Crunchyroll? There seems to be an extreme amount of censoring in Stardust Crusaders (black shadows, etc) compared to other anime or even the previous 2 seasons.

Examples:


Smoking
Cut body parts
Big wounds (eye stab, etc.)


I don't really understand. If perhaps the smoking thing is because Jojo is underage, Sanji smoked since "day 1" of One Piece (he was in his teens). The wounds I don't understand either, as some other anime don't censor large wounds (like Fate/Zero, which I watched while it was airing on TV).

Example of censorship in Stardust Crusaders:



Example of Jojo season 1 no censoring on huge wound:



I'm watching on Crunchyroll if it matters. Sometimes it's so bad I can't even tell what happened in the scene. Why is this? If there are any laws causing this, what laws and what do the laws say?
Edit: See @senshin's answer for the correct answer. This answer addresses the question assuming the version on Crunchyroll was the same as before. I will keep this here for general reasons as to why the series may have been censored on TV.

I don't have a definitive answer, but I can offer some guesses:


This season may have aired on TV earlier than usual so harsher censorship rules could have applied (I don't think this one is likely, but it's a possibility)
In the past few years censorship laws have been enforced more and more strictly. In July 2013 (before Stardust Crusaders) There was a big push for more self-censorship after a series of arrests in Core Magazine. Also broadcasters will send back episodes if they do not meet their expectations of censoring. These then have to be edited at short notice to be fit to broadcast.
With regards to smoking, The Japan Society of Smoking Control may have filed a complaint. They have been known to do so with other anime series, such as Nana Ref
Other groups may have complained about Jojo's content - In 2008 Jojo was under fire for having Dio reading the Qur'an and containing fighting scenes played out ontop of, and destroying, mosques. Ref - These scenes had to be redrawn.
The animators may have seen what way other shows were going and used them as a guideline for what to censor and what not to. It is true that Japan has been stricter on censorship over the last 10 years, and that the market is also moving towards a censored TV / Uncensored DVD setup.


I would imagine it's primarily broadcaster standards that dictate what Jojo can and cannot show. Stardust Crusaders was also on more Japanese TV networks than its prequel so it had more vendors to satisfactorily censor for.
