I never got even one legit lead. Not one.
I did, however, get quite a few scammers. One was quite scary. It was a local person, with a crazy project proposal, that kept trying to get me to meet them in person, in remote locations.
I nuked my Upwork account, months ago. Even though I hadn’t been on it for months, I would still get occasional scammer contacts. Most were pretty transparent. They didn’t make much effort to hide what they were about. Basically 419 approach.
Cofounders has been similar, but scammers try to get me to contact them outside of the system, and Cofounders has been quite responsive to my reports. I have kept my Cofounders account, as I have received legit contacts (none of which have panned out, but that’s the nature of the beast).
I did try TopTal, a couple of years ago, but that didn’t work out. I won’t get into it, but I don’t think we’re a particularly good “fit.”
Just a few days ago, I had to report a scammer on LinkedIn that had declared themselves to be one of my employees. It took LI three days to do anything, and they never acknowledged my increasingly frantic reports.
Like so many of these types of outfits, they provide no way to establish a way to actually contact people. You just have these one-way, opaque “Report” buttons, with no acks.
Scammers are very clever. I expect them to game this quite quickly.
It’s bad times. I pine for the “good ol’ days,” when there was some Honor to be found, but there’s no putting the candy back in that piñata.
