I think a better question is why is someone who has zero trade history (and thus no reputation to maintain) allowed to be on Default Trust?
Having this person on their trust list is a clear example of using shills with the trust system, however in this case the rating are going to show up by default to everyone.
Not exactly. cryptodevil has had an active presence on the forum for scam busting and apparently had trustable behavior, so someone on depth 1 added him to their trust list.
IMHO, I think that the trust rating was unfounded; the possibility that the OP was just a supporter of CloudMining.website is pretty plausible.
cryptodevil is a shill account whose sole purpose is to harass companies that he thinks is a scam as well as the customers of the companies that he thinks is a scam. It is one thing to warn others about a potential scam, but it is inappropriate to continuously harass a scammer, and even less so to harass someone who is doing business with such scammers.
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.
