As with anything - if there is money in something someone, somewhere is going to abuse it. That appears to be the case with LGR - it's monetized with ads and what not. I can't say for GGiD. I don't understand the thought process that goes with this in any other way though.
I get that some people get a kick out of pretending to be someone else for a short period of time. But to keep up the charade over the course of years? There's got to be more of a reason. No?
For what it's worth - I launched
lez.org yesterday. I hereby solemnly swear it's all me.
And my first post? All about LGR and DDiG.
