A bug in Facebook’s security system has shut down many accounts on the site. This was a bug in the Facebook Marketplace feature, which led to the closure of many users’ accounts for about a week.

In order for users to sell a variety of items through the Marketplace tool on Facebook, sellers must provide their identity to the Facebook authorities. That is, if someone wants to sell something using Facebook’s Marketplace feature, Facebook will verify their identity first. For this, some documents (such as photos, ID cards, etc.) have to be scanned and uploaded to Facebook.

These usually take up to 72 hours to verify. This may result in a 72-hour delay in the sale of products through the Marketplace tool, but the Facebook account will remain open. However, the error mentioned above Due Some Facebook accounts were completely locked.

Facebook says it has fixed the issue but users are still facing such issues. And some say they didn’t even use the Marketplace tool.

The problem is thought to be due to a bug in the Facebook tool created in an attempt to stop online fraud.

Have you encountered any such problems?
