Some journals allow you to specify reviewers to exclude. True that there is no guarantee about published work being good, but that is likely more about the fact that it takes time to sort out the truth than about nefarious cabals of bad scientist. I think the inaccessibility is for different reasons, most of which revolve around the use of jargon. In my experience, the situation is not so bad. It is obvious who the good scientist are and you can almost always be sure that if they wrote it it's good.
