Hello folks, during my daily "blogs" surf I found, in HyipNEWS.com a great article that explains much better my opinion than the small "text" I published in previous article.

Although I don't the like (much) the part of giving them power to block suspicious accounts, I am ok with it, because in practice it will be almost impossible to properly track money because all accounts are anonymous.
That's why I said these are mostly rules to look good on paper.

Now, what this article explains better (that I forgot/failed to explain properly) is the fact of LR created these rules because it's part of evolution of LR, and it must protect themselves against financial authorities, and potential claims of helping money laundering, like e-gold was accused of (if I understood correctly its story):

LibertyReserve has reached the level of development and the importance when there is a need to protect itself from possible claims by the authorities. By having this condition in User Agreement, they get a tool that will allow them to solve problems in collaboration with the authorities in extreme cases. And this, of course, does not impose any restrictions on work with clients (and almost all HYIPs are among them). Many other currencies and payment processors have the same rules and many issues simply must be talked over.
