SteamRep is a non-profit site that partners with community administrators to improve the safety of game-related trading. The site was created by Ðiego and, through the help of trusted volunteers and community admins, it has grown into the most popular scam prevention tool for Steam trading. SteamRep gathers scammer reports from a number of high-profile trade communities, as well as hosting its own forums to allow for reporting.
SteamRep supports DotA 2 trading and began taking scam reports from the DotA 2 community in June 2012, soon after the DotA 2 store was launched.
 Community Involvement
In addition to supporting numerous Steam trading sites and Team Fortress 2 trading servers, SteamRep has branched out into supporting other aspects of the community as well. SteamRep is a sponsor of the UGC Competitive Gaming League and sponsored the Fall 2012 Team Fortress 2 season unusual hat raffle. SteamRep is currently planning another charity DotA 2 event with other DotA 2 communities.
In February 2013, SteamRep partnered with other communities and trading sites for the DotA 2 Charity Invitational: Heroes Helping Heroes. The charity event raised £2,319.14 for the Make-A-Wish Foundation.

 Site Layout
SteamRep's central focus is a search box where a user can search for a user by SteamID 32, SteamID 64, custom URL, or Paypal email. Above the search box are tabs where a user can access various lists and tools. Below the box are buttons to report scammers or repeal a scammer tag. The home site also features a real-time listing of latest viewed profiles and latest marked scammers, as well as a listing of communities which support SteamRep. Statistics regarding the site are listed as well as a button to make a donation.
There are tabs at the top of the site which link to lists of middlemen and community admins as well as information about the API, link to the forums, and a Frequently Asked Questions (FAQ) page.
