Streaming platform, Youtube has decided to ban all comments under videos aimed at children in a bid to prevent pedophiles from leaving predatory comments.

The comments became such an issue that several brands pulled their advertising.

Trusted Flaggerstold the BBC back in 2017 that there could be up to 100,000 active predatory accounts on the site, and that the report feature on the site is not effective in shutting down these accounts. The number is thought to be higher still.

"Over the past week, we disabled comments from tens of millions of videos that could be subject to predatory behavior. These efforts are focused on videos featuring young minors and we will continue to identify videos at risk over the next few months. Over the next few months, we will be broadening this action to suspend comments on videos featuring young minors and videos featuring older minors that could be at risk of attracting predatory behavior," Youtube said in a statement.

"A small number of creators will be able to keep comments enabled on these types of videos. These channels will be required to actively moderate their comments, beyond just using our moderation tools, and demonstrate a low risk of predatory behavior. We will work with them directly and our goal is to grow this number over time as our ability to catch violative comments continues to improve."

The site is asking users to continue to flag predatory comments to help them to flush out the accounts. It is reported that it could take several months before the changes are complete.
