Hello Olivier,
Thanks for sharing this, i recall you actually raised this during one of our meeting and i really did not consider the implication this much. Its interesting how people pay such huge amount and go through the application processes to end-up utilizing the TLD in such a manner. Within the numbers community, resources are assigned/allocated on "needs" basis. Are there polices that reviews/check usage of TLDs against the intent of requesting the TLD initially? I guess that could be where to approach this and reduce the growth of such abuse.
