For those of us unfamiliar with the world of YouTubers, the video platform and its celebrity culture is a strange, intimidating land.

Basically, all we know is there is a lot of drama and sometimes that drama (remember James Charles and Tati Westbrook?) goes beyond the YouTube bubble and enters the consciousness of well, everyone else.

Fans and social media users have dug deep to the depths of old YouTube, podcast and Twitter content to find offensive, racist and disturbing incidents that are now popping up all over the internet.

In the last couple of weeks many different YouTubers, including some of the platform's biggest names, have apologised for problematic content from their pasts, either on their own accord or after being prompted.

The names Jenna Marbles, Shane Dawson, Jeffree Star and Tati Westbrook in particular, have been all over social media recently. We've broken down each of the issues surrounding these names, plus a few more.

Tati Westbrook.

You might recognise this name from the time she created what was one of 2019's best feuds, and Tati Westbrook is back baby, to take part in one of 2020s too.

On Wednesday AEST, Westbrook uploaded a video to YouTube titled 'Breaking My Silence', a 40-minute tell-all throwing her ex-mates Jeffree Star and Shane Dawson well and truly under the bus.

Last week, Dawson denied that she was behind her 2019 drama with James Charles. But in her video, Westbrook said it was in fact Star and Dawson that orchestrated the whole thing, because they were "bitterly jealous" of Charles' success.

"Back in 2019, Jeffree started talking a lot more crap about James Charles than usual. It seemed that doing so had become his biggest obsession," she told viewers.

"Over the course of the next few weeks [Dawson] and Jeffree fed me so much new information that I felt sick. Almost every day there was more information and new allegations. Eventually, I started believing what they were saying, because they said they had evidence.

"It wasn’t enough for me to contact the authorities, it was enough to scare me."

She said she made the video "as a result of all of the poisonous lies that were fed to me by Shane Dawson and Jeffree Star".

She apologised to Charles as well as others who had found themselves in feuds with Star, whose side she took.

After the video, Dawson posted and quickly deleted "“THIS IS A F**KING LIE AND I’M LOSING MY MIND!!!!!!!!!!" on Twitter. Star is yet to respond.

Jenna Marbles, real name Jenna Mourey, announced she was quitting the platform in a video to her 20 million subscribers on June 25.

Marbles was one of YouTube's first and biggest stars, spending the last decade of her life being a YouTuber.

In her final video, the 33-year-old apologised for her past controversial videos, including one featuring what viewers perceived as blackface impersonating Nicki Minaj (though Marbles said she was not wearing any makeup or extra fake tan in the video). Other videos included a rap that disrespectfully imitated Mandarin, and sl*t-shaming. According to Forbes, the hurtful content has been private, and therefore not visible on her channel, for many years.

"I think I'm just going to move on from this channel, for now," she said in her apology video. "I don’t know if that's forever. I don't know how long that's going to be... I want to make sure that the things that I've put into the world aren't hurting anyone.

"I'm ashamed of things I’ve said and done in my past."

Marbles said she has made her own content private because she no longer thought it was appropriate.

"I think there was a time when having all of my old content exist on the Internet showed how much I have grown up as a person, which I'm very proud of," she explained, however, "I think now it's hard for that content to exist at all."

Jenna Marbles' exit from YouTube - what people are seeing as ' self-cancellation' - has received a mixed reaction, but fans and content creators have argued Marbles had clearly grown her beliefs and ethics since her early videos and took accountability, unlike many others in her industry.

I think it's vitally important that we tell creators when they are doing harm. And I have watched some creators react to that by listening and changing, while others have cried a bit in an apology video and then gone right back to making shitty stuff that hurts people.

"I really strongly believe that we should be judged not by how we acted when we were ignorant, but how we responded when we were informed. By that measure, Jenna Marbles is head and shoulders beyond a great many YouTubers," Hank Green, creator of VidCon, tweeted.

YouTuber Sky Williamssaid "we need to celebrate reform and change instead of condemning the past... She's showed her growth in her work and life".

FUCK this @Jenna_Marbles shit is breaking me up. we need to CELEBRATE R
