ES is virtually useless for the punter. Some girls repeatedly upload fake pictures and despite getting reported, nothing happens other than a new set of fake pictures get uploaded, then get reported...
Other girls upload fake pictures - they stay up for a couple of days while they are "authenticated". In fairness sometimes they don't get authenticated and the girl then uploads a new set of fake pics, which stay up for a few days while..... you get the picture, one way or another fake pictures get to stay up for ages and no action appears to be taken against the repeat offenders.
Recently there has also been a lot of complaints on their forum from punters about negative reviews being deleted - the problem is I can't link the negative reviews or threads because... they've all been deleted. Make of that what you will.
