WHY INTERNATIONS IS BLOCKED IN UAE? (Dubai)

My friends and contacts and soon to be contacts are complaining that they cannot access InterNations.org anymore since last Saturday. I wonder why? Comparing to other social network site, I consider InterNations as Immaculate and spotless in terms of indecency. Well it seems that InterNations has reached its peak that it is now being spotted by others and now it was blocked for no apparent clear reasons. Inshallah, we can still access soon.
