Basically, over the last few years from what I've seen is that Iranians are involved in a large number of domain thefts. As well, the Iranian government does not cooperate with Western countries in dealing with these thefts.

There is the latest case here with jj1 / Get+1
11 LLLL,com Offer Wanted

Another recent large scale theft by an Iranian:
Lots of Stolen Domains : Domain Bits

Last month Twenty.net was stolen by an Iranian.

In September ESE.com was hijacked by an Iranian.

I think it turned out that there was an Iranian connection to this theft in March:
Fucked Up - The Theft of Fucked.com and Pornos.com : Domain Bits

Who knows - it could all be the same person or group of people from Iran.
