Until now, I only focused on the changed description for Negative feedback and didn't really notice how Positive changed. I used to use
my non-DT1 account to leave feedback on successful deals, but under the current description, I can't do that anymore.
Someone making many trades without issue is usually an indication they will not scam, however additional information is needed to make this determination.
A neutral rating would probably be more appropriate for a single successful trade, and perhaps several successful trades (that appear to be mutually beneficial) would warrant
consideration of giving a positive rating, and a person unexpectedly being able to scam you (due to your mistake), but doesn't is probably going to warrant a positive rating most of the time, but good judgement should still be used in these cases.
