Hola,

los RIRs no tenemos poder de policía ni rol de oversight. Somos
facilitadores de muchas actividades debido a nuestro contacto cercano
con la comunidad de operadores, pero no tenemos ningun instrumento de
sanción que aplicar. Y personalmente, creo que está bien que eso sea así.

Creo que la protección contra este tipo de ocurrencias pasa por otros lados.
