The FTC is going after a reseller alleged to have nefariously snatched up more than 300,000 tickets to various events.

The US Federal Trade Commission sued ticket reseller Key Investment Group for evading purchasing limits to buy up thousands of tickets to live events including Taylor Swift’s Eras tour and resell them at a markup,

Key Investment Group said the FTC is misapplying the Better Online Ticket Sales Act, a 2016 law which it said was meant to target malicious software, not legitimate resale businesses. Key Investment Group sued the FTC in July to try to prevent the agency from using the law against it, saying it uses human employees — not bots — to buy tickets.
