The app will ban any accounts who are repeatedly uploading videos after the disturbing footage, which was originally uploaded to Facebook, made its way around TikTok.
They said in a statement: "Our systems have been automatically detecting and flagging these clips for violating our policies against content that displays, praises, glorifies, or promotes suicide.
"We appreciate our community members who've reported content and warned others against watching, engaging or sharing such videos on any platform, out of respect for the person and their family."
Facebook took the video down last month and were able to remove copies and uploads of the clip as well.
Facebook told BBC News: "We removed the original video from Facebook last month, on the day it was streamed, and have used automation technology to remove copies and uploads since that time.
"Our thoughts remain with Ronnie's family and friends during this difficult time."
Several parents have expressed their concern about their children seeing the footage on TikTok, which is used by millions of young people.
