In cases like this you should be able to 'REPORT' a system. MyFxBook should only remove the system if the developer contacts them and objects. Just because someone is using a commercial systems should not disqualify them. There is also an art to OPERATING a robot that shouldn't be ignored.
Well, its not a matter of quality... as I said prior 'any quality' should state this...
To get this straight, in most cases one would violate the TOS (Terms of Service) of a developer/vendor of a commercial system if such signals would be provided by a third party if not authorized. Thus its an infringement where the 3rd party and AutoTrade would be liable.
A simple report feature would help initially but not solve such cases. From a developer point of view i would take legal action accordingly.
If AutoTrade is serious about their business they should have for their own protection a proper TOS/Registration/Verification (Broker alike) in place.
Again, lets not see AutoTrade becomming just an other 'junk' hub. It would be a pity if a great opportunity would be missed.
