WhatsApp on How It's Fighting Bulk Messaging and Suspicious Accounts

Ahead of India's national elections later this year, WhatsApp is trying to wrangle bulk messaging and suspicious accounts. From a report: At a press briefing in New Delhi early today, company executives said they have built a machine learning system to detect and weed out users who engage in inappropriate behavior, such as sending bulk messages and creating multiple accounts with the sole purpose of spreading questionable content on the platform. Automated suspicious accounts and people who seek to create havoc are barred from the platform at various stages -- at the time of registration, while messaging, and when they are reported by others, the company's executives said.

Overall, WhatsApp bans about 2 million accounts on its platform each month, a spokesperson said. To address this issue, a machine learning system uses learnings from the company's past dealings with problematic accounts and from specific scenarios engineers followed when taking down accounts, said Matt Jones, a software engineer at WhatsApp. This machine learning system has reached a level of sophistication that allows it to ban 20 percent of bad accounts at the time of registration, according to the company. Seventy-five percent of the 2 million accounts WhatsApp bans in a month are handled without human intervention or a report filed by a user, said Carl Woog, a spokesperson for WhatsApp.
