By posting that link here, you are like telling more pple about it.
There are 101 such sites out there, if your pics are being leeched there, you can send the administrator a mail. If they refuse to remove it, only then you consider further actions. In fact, that's what we did the last round, I think.
I dun see how it can be lawful... by editing other people's picture and placing it on the site without permission, it's already illegal.
Under Singapore's intellectual laws now, that is an automatic infringement whether the owners of the site are aware of it or not. And by editing the pictures discriminately, they can also be charged under a clause for vandalism.
Also, some other sites charges money for transfering the pictures to MMS for handphones, though the service is perfectly legal, the content of transaction is not.
