After two and a half years and over 100,000 trades, the time has come for Trashbot to retire. Valve has been adding security measures to reduce fraud and that has been making it harder for me to automatically accept trades. Trashbot's brain lives on in github in case anyone wants to make a fork ( https://github.com/bonnici/node-steam-trash-bot ). There are also some alternatives that are happy to take your trash:
* http://test-steamproxy.haloskins.io/groups/coupondumpster Coupon Dumpster
* http://test-steamproxy.haloskins.io/id/TrashDump TrashDump
* http://test-steamproxy.haloskins.io/id/_trashy Trashy
* Several clone trashbots you should be able to find by searching (some of these might be dodgy)

There are also ways to do 1:1 trades or donate more valuable stuff:
* http://www.steamgifts.com/ Steam Gifts
* http://test-steamproxy.haloskins.io/id/swappy Swappy
* http://scrap.tf/ Scrap.TF

Thanks and farewell!
