"Ok Bob, you're hired. Normally we'd send you a computer and all the other equipment you need, but our vendor communications are all fucked up. So we're going to send you the check we would have sent them, you deposit it, then you order the equipment from them. Plus that way your name is officially on the purchase and you own the equipment after 15 weeks! Why don't we just send the check to the vendor? What, are you calling me a scammer? How dare you!"

The scam is that they are secretly the vendor and they never send you the computer equipment that you buy with your own money. The money from the check they sent gets taken back by the bank because it's fake.

Ah that is truly a very obvious scam

My friend, if you have time to ask for a tl;dr and ask follow-up questions, you have time to read the original post. Off you go.

The original post here is just a long string of original documents and background information, leaving the reader to read the entire thing to piece together what happened. Providing a summary in the introduction is a key part of effective communication.

Definitely took less time to type these few sentences than it would take to read that wall of text
