One might reply that the media is also in need of reform. That is currently a hot topic in the UK
after the Leveson Inquiry.
The question is, “Who will do it?” Can any organization be trusted to regulate itself, or can the regulator be trusted to be impartial.
The more I think about the idea of “Reforming the Sangha,” or regulating it in some way, the more it seems like just more suffering caused by the desire to control conditions.
Ajahn Khemadhammo in the UK, is actively trying to promote the formation of some kind of regulatory body for the Sangha in the UK — maybe something like a monk's passport, which they already have in Thailand. However, I just don't see what benefit it could have.
The number one reason why there is corruption in the Sangha is because monks accept and make use of money. They could not do that if the laity did not give them money. If monks could not gain access to money, there would be less incentive for corrupt individuals to enter the Sangha. Greedy individuals would not tolerate the restrictions of monastic life just for the sake of free food and lodgings.
The only way to bring about any significant change in the Sangha is not through regulation, but through education. Lay Buddhist and monks need to learn what the Buddha taught — only that will stop the religion from degenerating. That's not going to happen universally — it is down to individuals who want to follow a pristine form of the religion to educate themselves in the theoretical and practical aspects of the Dhamma so that they cannot be deceived by bogus or corrupt monks.
