How will the cops find the OP

Okay, so on another Sub-reddit i saw a post where someone complained about a business that treats their employees like salves. And everyone in the comments asked OP to reveal the name of the company. But OP wasn't willing to say the name of that company because he thought that he might get sued for defamation....

My question is, if the OP's account was a fake newly created account(fake email/fake username), that doesn't have any of his personal info recorded.. …
