Job posts get checked for scams.

When someone posts a job on the website, a filter checks it for common scam patterns. If something looks wrong, a person reviews it before it goes live on the site.

Every job listing also shows a safety warning with tips on what to watch for. Too-good-to-be-true pay. Requests for money upfront. Vague job descriptions. The warning is right there so you know what to ask about before you apply.

It's not perfect, but it catches the obvious stuff.
