Yeah, but that doesn't mean they're necessarily legitimate once they're established. It also doesn't mean that a source that doesn't gain this board's approval isn't legitimate.
Since we're talking about reddit, tone of this board reminds me of /r/hailcorporate on reddit, which is routinely made fun of because in trying to question everything, the members read motivations into posts which are not there. There was a hilarious post about breadsticks where someone thought a joke about "unlimited breadsticks" meant that a poster was an Olive Garden shill. Every other board made fun of them for this.
Posters here have negativity bias. In other words, one negative comment will be given inordinate amounts of trust, because posters are so wary of being scammed. Usually one claim of "this gear is bunk" is enough to cause panic about a particular product.
You should take neither negative NOR positive comments at face value.
