Nothing have more audience then EI. I would suspect the reason they moving is because the fee they pay for advertisement here comparing with twitter and others where is free. Is free for a reason and paid here for a reason. To keep the website up need lots of CEO wich cost money but is worth it. at some point, i advertised and in other places but my phone didnt ring much or not at all there. The only calls I got was form guys who found me on EI. this was my particular experience with advertising in other places. Plus personally I dont like at all the purple site because they ask lots of private things and official documents etc etc plus they will put my rea nationality in their website against my will. I dont feel comfortable to send my passport, id, residence proves and other things to unknown people, a website u can contact only by email. NOt a real person to talk with, not a phone number, plus the last time as i remember after I bought credits, I changed my mind and cancelled the transaction but guess what ..next day the transaction went thru lol and immediately when i tried to log in in my account their ..my account was suspended. so after they took my money they suspended my account and asked me to send all that privat documents to activate again. When I asked what happen with my money they took and the credits i bought... no answer. its easy to not answer when the only way to contact them is an email.
So no, I will not go to advertise elsewere, I have no time to manage Twitter accounts every day to post and other things, no other dodgy websites, EI worked for me from 2013 so I will stick with it.
And about EscortFun website is a good idea, why not.
