You can try to flag the listing under the more tab. Be aware that scams do exist; be mindful that such web sites are third party sites, they are not real estate companies and are used for advertising purposes; the information is fed by various sources, therefore data is not really verified. If you choose not to work with an agent of your own always verify ownership before exchanging any money/personal information--make certain they are who they claim to be. Never wire any money, if it sounds too good to be true, it is. For scam related information see link.
