Looks like OPs post was flagged. I have also seen this on multiple ocations. To me this is REALLY fishy. Since the janestreet fraud there has been a massive campaign online to downplay all negative comments, disable comments on JS videos, and overall radio silence.

I know some long term ocaml users and i can tell you that there is stuff boiling under the hood. Many are very much NOT HAPPY with JS and what they did.
