Nothing, however it is pretty obvious their business model is ticket scalping, reselling freely available tickets with a hefty markup from a squadron of websites designed to appear as if they are official rail company sites to catch out the unwary and ignorant.
This may not be as profitable as full scale fraud by taking money and not providing anything but it has a distinct advantage of being legal enough that they aren't in any danger of having an early morning visit from folks with riot shields.
That's exactly what it is. Had they been based in the UK, it would have been a matter for Trading Standards to investigate, however even then I would think that they would be told to highlight that they are a third-party provider.
Whilst what they are doing is not in the spirit of the rules in NRCoT, I struggle to see how it could be court enforced, outside of an extremely strongly worded cease and desist on the grounds of using railway marks without express permission.
I would say that the only real way to stop this would be to have it highlighted to the public, possibly through a media campaign by RDG urging the public to check that their ticket provider is legitimate, and how to confirm this.
I've investigated outfits like this for the media before, however in the aviation industry. It's rife with unlicensed third-party ticket peddlers and they tend to fold pretty quickly when under scrutiny. I might do a little digging on this outfit.
