Reminder for those getting client inquiries: people asking you to run code on your system before they've given you any money is likely a scam. Get real contact info, get a face to the name, and do your best to vet the client before you start doing anything like installing packages.

@Contra HQ does a really phenomenal job of handling issues once you flag them, if they don't catch them by the time you open your messages. There's a handy 'Report' button. Best to use that and not even let the scammer know you're onto them. Stay safe, fake clients are everywhere. The only obstacle to you making more money is losing it all to a scam.
