A serious Twitter debate has erupted about white social media influencers who are 'posing' as biracial women to gain a larger following, with dozens of users chiming in to voice their horror at the behavior.

The topic first earned attention last week when a Twitter user accused a Swedish model and influencer named Emma Hallberg, 19, of darkening her appearance and altering her hair to appear more black or biracial.

The revelation sparked a conversation online about cultural appropriation and what can be considered blackface.

Controversial: Swedish influencer Emma Hallberg, 19, (pictured) was accused last week of purposefully spray tanning and altering her hair to look biracial

Shocked: The controversy with Emma first started when one follower was told that the influencer was actually white instead of biracial

Revelation: The follower (pictured is her tweet) then shared the interaction so other people could know about Emma's true ethnicity

Strange: Emma has more than 200,000 followers on Instagram, some of whom thought the influencer was biracial instead of white

In pictures she shares on Instagram, Emma appears to have a deep tan, full lips and curly hair, despite being white.

But other images and video show that she applies foundation several shades darker than her own skin to get that 'tan' look.

One of Emma's followers also revealed last week that the influencer sleeps in braids to give her hair 'texture', but the person was unsure if that would be considered blackface.

Inspired, someone messaged Emma on her Instagram account about her skin color.

'Hey Emma is it true you're white...and just posing as a colored person?' the message read.

Emma, who has more than 200,000 followers on Instagram, responded: 'Yes I'm white and I've never claimed to be anything else...I'm not "posing" as a colored person as you claim. I've never tried to be or look black. I was born with naturally curly hair and my skin gets very easily tanned in the sun!'

But this explanation did not appease people who believed the woman was going out of her way to purposefully appear biracial.

Upset: The conversation between the two women continued as they discussed if Emma's appearance could be considered blackface

Upset: The woman, Dee, continued to update her followers about the conversation so they could know more about the influencer they were potentially following

Interesting: Old pictures of Emma, in which the woman has a lighter skin tone and straight hair, started to circulate

In an interview with Buzzfeed, Emma explained the controversy and why she believes these claims are false accusations against her appearance.

'It made me sad that some of my natural features are hurting and upsetting people,' she told the news site.

'It also made me upset and scared that I can't look the way I look naturally, without receiving false accusations, hate, and threats. I do not have any specific intentions other than [to] show my passion for makeup and fashion.'

Emma also claimed to the news site that she never uses self tanner and just naturally has a 'deep tan.'

But not everyone has accepted that answer, including one person who said she is also from Sweden.

'I'm 100% Swedish like her,' a woman named Amanda wrote. 'There is no way in hell that's her natural tan.

'I wouldn't even get that tan with three layers of spray tan cause we're white AF! Plus she only has like two months to get tan in Sweden. It's cold and dark her 90% of the time.'

Need to know: One follower went as far as to message Emma on Instagram after seeing the Twitter thread. Emma said her skin naturally tans that dark

Problematic: Victoria Waldrip, 18, who is known as Woah Vicky online, is another controversial white influencer who poses as biracial

DailyMail.com has contacted Emma for a comment about these recent allegations.

Of course, Emma is not the only influencer to come under attack for what has become known as 'blackfishing' — which means posing as a light-skin black or biracial person.

Another influencer who came into the limelight this past year for posing as biracial is Victoria Waldrip, 18, who is known online by the name Woah Vicky.

She was the center of controversy last year over claims she made that she is black. She was also accused of consistently appropriating black culture in videos and pictures. The influencer even went as far as to do a 23andMe test to prove her heritage.

The conversation last week inspired a woman named Wanna Thompson, who is a freelance writer, to start a Twitter thread calling out other white influencers allegedly posing as biracial or black women.

'Can we start a thread and post all of the white girls cosplaying as black women on Instagram' She wrote.

'Let’s air them out because this is ALARMING.'

Not having it: The conversation inspired freelance writer Wanna Thompson to create a thread of other white influencers posing as black women

Insane: Other followers shared white women online who also appeared biracial

Another one: There were multiple white influencers targeted in the post online

Multiple followers commented on her thread with their own examples of women on social media modeling exaggerated features typically seen on a black woman — including the larger lips, tanned skin and curly hair.

In an interview with HelloGiggles, Wanna explained why this conversation was important to bring to light to people who might be following some of these women online.

'White women want the benefits of being black without dealing with the responsibilities that come with it,' she said.

'They see the features that black women are blessed to have, and they literally do anything to obtain it. This form of blackface is even more offensive because they’re not even trying to hide it.'

Wanna hopes these conversations online will help people realize the trends black women have catapulted into beauty and fashion industries.

'It’s clear that a lot of Black women are being overlooked for white women, but I believe that narrative will change because I refuse to stay silent on the matter,' she said.
