Abandoned by original owners. Now just a hub for scammers trying to get your email address an 419scams. Deleting your profile is not the end as you will be flooded by spam as soon as you do.
Watch out for shiny start ups with poor business models. They should have shut the site down as soon as they failed, instead they sold it to crooks and put people at risk.
