Jim Browning (a pseudonym) has a very entertaining channel where he turns the tables on internet scammers, like those who send pop-up ads to websites claiming they are Microsoft and there's a "virus" or something nasty and the only way to get rid of it is to call a number. When the victim calls that number they are cajoled into granting the scammer remote access to "fix" the problem and then charge hundreds of dollars. Some are worse than others, like some actually use access and verbal trickery to the less tech savvy to hack into victim's bank accounts and help themselves to whatever they want. Brownings M.O. is to use his technical skills to actually hack back into the scammers computers to gain access to all the scammers operational and financial files that are on their servers.

In this case he goes after a scam operation that disguises itself as a travel agency. They do the typical Microsoft tech scams as well as imitate Amazon and trick people into buying them gift cards. But they also imitate Delta Airlines. In the below Part 3 of 4, a Delta SkyMiles Card holder (probably an AMEX card) tries to use miles to purchase flights and the scammer asks the victim for his DL password. Luckily DL.com seems to be set up to detect non-customers and in this case the scammer couldn't get into the victim's DL account. The part about DL starts at about 11:00.

Part 3:
The happy ending is as a result of these videos the operation has been shut down by authorities and its operators have been arrested.

Some might feel hacking into another person's account is equally immoral no matter how awful the person being hacked is. You might feel differently after hearing this gut wrenching call in this same call center scamming a child in a video by one of Brownings partners:
