If i had to guess its because theres too much random crap in it. A rep thread should JUST contain your ID64/identifiers and a way to make sure its really you. Theres no need for anything else (stock/items sold/Trade history).

EDIT: Its probably because you're saying you have done previous trades (i.e. quoting Rep) without providing any proof/source that that rep existed in the first place.
