The current hot topic across Second Life forums is ZF Redzone, the device aimed at preventing griefers, copybotters and alts from causing mayhem and getting their hands on your wares. The aim at first glance is noble, the execution is far from it.
There are signs that all is not well with this system from its description, where it claims to eject and TP home intruders, often crashing them. That right there sets red flags. Another red flag manifests itself in the shape and form of the creator advising in the comments of the reviews that it’s a good idea to ban your competitors from your land because they will spy on your or send alts to do so….alarm bell city, this is getting into the realms of paranoia as a marketing point.
However, there are features of this system that would be useful, the fact that it can ban more people than the inworld tools being one, being able to manage access controls from a website being another.
