I am fairly certain that I know who the OP is and I don't think it is productive to make ad hominem attacks against the OP, as I would argue that he is probably one of the most trusted people around.

I would say that I agree that Mexxer-2 and Lutpin are strange choices for being in the Default Trust network. I would also say there is a high chance they are the same person.

I somewhat get the feeling that some people are trying to make a name for themselves as being a scam buster. They are doing this by stretching the definition of a scammer and leaving negative trust for people who probably do not have the drive nor motivation to defend their name/reputation, even though what they are accused of doing, even if true, is really not scamming.

I would note that a good number of the "Mexxer-2 and Lutpin" threads have resulted in no additional negative ratings being added to the accounts of those complaining, and in a decent number of instances the ratings have been removed. On the other hand, it was fairly rare that a rating that I left was inappropriate, and as a result very few ratings needed to be removed that I left and many of the "QS" threads resulted in additional people looking at the evidence and leaving additional ratings on those complaining.
