Crossroads Review, formerly found here, has vanished. As has their Facebook page and Google + profile, which at first suggested a deliberate disappearance. At Crossroads, paid reviews cost $50 and review blog tours ran $200-$700.As far as I can determine the site operated from late 2011 until early this month.
However, the main person behind Crossroads seems to be Jessica Porter, whose twitter account is still posting as of today and states "At the moment Contessa at the Crossroads is down so please find us over at The Witchy Contessa!" Authors looking to follow up as to when/where/how they will get what they paid for should monitor the new site "Witchy Contessa".
My advice to Jessica would be: if someone has paid you hundreds of dollars, it is wise to send them updates and explanations about outages immediately to avoid suspicions that you might have cut and run.
Given the comment below, it seems according to one author she did in fact deliver neither a tour, nor a refund. You can't cancel a service and keep the fee.
