Just because some people have given bad reviews doesn't mean a recruiter is generally bad. And thinking recruiters all suck at their job is going to cost you in the future, assuming you are even worth being headhunted. Most, if not all of my friends who were placed in MC/WS firms from local B4 went through a recruiter. You have to understand how their job works (esp how they are paid) to make sure their interests are aligned with yours. Insofar as that is true, you can trust them.

I get the feeling that the people on this forum who have been ghosted just have a CMI CV or suck at their job and they couldn't be placed for that reason. Recruiters can't work magic.
