CL is not well monitored, but hey it's free and not flashy. From exp. the majority of postings are legit.
I believe OP is asking about all the job listings for traders on CL. Most are either training firms or deposit firms. You will not find ads on CL for places like NYFS or Jame Street, etc. Legit firms should at a minimum include the name of the firm in their ad. Also, there is now a listing fee in most metro areas to post jobs on that site - no longer free, per se. What city are the ads?
That's not true. I've seen Citadel place ads on CL as well as reputable firms like Breakwater. I agree, CL seems to be a hotbed of FX firms based out of FL. But anyone with an IQ of 35 can filter out the real firms from the scams. And if you can't, that's called Darwinism.
