@Andrew Boon: You lack any understanding at all of these modifications.

These modifications are developed entirely with the intent to deceive people into joining a web site which appears active, but in reality, is empty. They are used by those who instead of using honest effort to build their community, decide to simply hit a button and bingo: thousands of profiles from around the world, with the option to cheery-pick which are shown as online. I should add that many web sites using this tactic see more are also pay-to-join, meaning people are deliberately being deceived to join an empty web site, and pay for it, which is most definitely illegal. I should need not mention as well, that the developers' of these modifications permission to use such photos and various information is most certainly without consent.

I would now like to highlight the Profile Grabber modification, which, as described, is meant to scrape profiles from popular social networking web sites such as Myspace and Friendster, and add them to the web site running the modification, entirely without the consent, or even knowledge of the original profile owners. This is highly illegal, and Myspace and Friendster have already been contacted about this modification, and are investigating it, per a response by their staff to an email alerting them to the modification's existence, as well as information such as your unwillingness to remove them.
