cryptodevil has zero trading history and as a result if he is incorrect about a rating his reputation will not suffer (because he has zero reputation to start with), and as a result he has no incentive to give out ratings that are reasonable, supported by facts (instead of speculation), and to remove a rating when it turns out he is wrong.
There is the threat of being removed from the default trust list, if his ratings are unreasonable.
That should be sufficient.
You have got to be kidding me
Being on DefaultTust is a liability if anything because it attracts a lot of drama towards you when you leave a negative rating. Even if you never leave a negative rating, others will try to figure out what it takes to get a positive rating from you and then farm trust from you.
It is however unlikely that cryptodevil is going to get removed from DT because the ratings he leaves are nearly identical to those of ThePhwner and dooglus, except most of the time, only one of them will leave a negative rating. This means that none of them will attract sufficient attention so that other level 1 DT people will not exclude any of them, and that the level of controversy associated with each of them is reduced by roughly 2/3, which is substantial.
By having zero trading experience (at least from the account he is leaving ratings from), he lacks the experience to be able to reach a middle ground with others, and lacks the ability to show that he has a history of acting reasonable.
