Buyer describes illegal activity

Look I understand FF is a fetish site, but it's FEET. A lot of times it gets more explicit and that's whatever. I just had a buyer describe to me something insanely uncomfortable and illegal that he'd want to do to me after hours in my workplace. I don't want to post it bc it could be triggering..and I get it, people are going to say weird things, but you should be able to have some sort of filter as an adult. I reported it to FF when I blocked him, but I don't know if it will go anywhere bc he had a ton of purchases and reviews. Idk just a little shook up after that interaction..
