On the contrary, since the trust system is designed for, to quote theymos,
"getting a general idea of someone's trade history and trustworthiness in one convenient location" [reference], and taking into account the evidence presented by Ratimov, it makes perfect sense for a neutral tag with a reference to this thread.,
Unless there are concrete evidence we have no right to write anything in others trust wall even with neutral feedback. The forum gave too much freedom to the users who are regular (us) just to do what we like wherever we like.
These days I see too many neutral tags which actually can not be considered as neutral but a way to underestimate others. Most of it are given to achieve two agenda:
1. Of course to underestimate the users who they do not like
2. To build up their own reputation proving that they are always active to find wrong doings.
Both are bad since it's all are in personal level.

For the record this was mentioned to consider in general. Sorry I failed to point it out so you thought it was meant for this particular case.
