I run a fairly well-known organic chemistry website. Occasionally I receive notes from amateur chemists who want advice on various aspects of lab prep. Sometimes they are amusing, like getting late night calls from amateur CBD chemists. Other times they are scary. Two of my correspondents turned out to be so completely in over their heads there was no helping them.

One guy, a former electrical engineer, was making elemental chlorine and pirahna solution in his condo. The other was convinced he was close to finding a new drug for curing cancer - he sent me a Chemdraw file with impossible structures - and was hell bent on fluorinating a compound using DAST.

I had to cut off all contact with both, lest it be seen that I was aiding and abetting their reckless behavior...
