Rand Research Survey Secret Shopper Doing Fraud on Career Builder, claming to be secret shopper later Jacksonville Florida

These people have scam written all over them. How can somebody post on career builder a few days ago, then get a large check printed and send it to you that quick?They don't even have a website, and are using other's names. Rand Research.org is not Rand Research Survey, and it's no such thing as Rand Research Survey. Secret Shopper also has a different Logo than what's on the letter that came with the fraud check. It doesn't say The Premier Mystery Shopping Company, Atradition of excellence since 1990. Also, why send a big check, but expect somebody to only take a small amount and send the rest to another person using Money Gram?I just saw another post from June 10th that said Western Union. Child Bye! I'm not getting caught up in that, and I also alerted the credit union they tried to use as bait. And the Post Office knows and told me to file a complaint with USPS Inspecter.
