Conclusion and key takeaways 

What is social media screening?

Social media screening is the process of reviewing a candidate’s public online presence to flag potential risks or red flags. It’s typically part of pre-employment checks and can reveal behaviours that wouldn’t show up on a CV such as hate speech, illegal activity, or discriminatory comments. 

When done professionally and ethically, social media background screening gives an added layer of insight to protect your workforce and brand. That’s why 85% of recruiters now include social media screening in their hiring processes, according to our background checking partner, Neotas.

While many businesses still rely on informal Google searches, there’s a growing shift towards structured, ethical checks. That’s where formal social media background screening comes in. It removes bias, reduces the risk of discrimination, and helps employers focus on what really matters.

How does social media screening work?

Companies usually work with a specialist provider who uses a combination of technology and human analysis to scan a candidate’s publicly available social media activity. The screening doesn’t access private messages or require the candidate’s login credentials. Employers then receive a report outlining any relevant content, flagged against categories like extremism or explicit content. 

At Zellis, we partner with Neotas to provide this service, using its AI technology to accelerate and de-risk the process. 

What do social media checks look for?

Social media background checks look for content that could pose a reputational or cultural risk to your business. They’re not about policing personal opinions or lifestyle choices. Instead, they flag serious concerns – harmful behaviours or values that clash with your workplace standards.

Common red flags include:

• Hate speech or discriminatory comments
• Threats of violence or aggressive behaviour
• Sexually explicit or obscene content
• Promotion or evidence of illegal activity
• Toxic or extremist views
• Harassment or bullying
• Misinformation or harmful conspiracy theories
• Inconsistencies with declared employment history

What are the benefits of social media screening?

Social media screening helps you make safer and more informed hiring decisions. Flagging high-risk content early reduces the chances of reputational damage, toxic behaviour in the workplace, or costly misconduct. It also strengthens compliance and due diligence processes – especially for regulated roles. 

When done properly, social media background checks offer clarity without invading privacy. At Zellis, we believe it’s about protecting your people and your culture, not policing opinions.

Is social media screening legal?

Yes – but only if it’s done fairly, lawfully, and transparently.

Under UK GDPR, you need a legal reason to process a candidate’s personal data. For most employers, that fall under “legitimate interest”. However, it must be necessary, proportionate, and balanced against the individual’s privacy rights.

You can’t require candidates to hand over passwords or log into private accounts, as checks should only cover content that’s genuinely public. You also need to inform candidates about the check, ideally through your privacy notice, and get their consent.

What’s more, it’s unlawful to base hiring decisions on protected characteristics such as race, religion, sexual orientation, or political beliefs. That includes what you might discover through social media. Using structured criteria and a third-party screening provider can help reduce this risk.

Is social media screening ethical?

It definitely can be – when done the right way. Ethical social media screening respects privacy, sticks to public content, and uses consistent criteria to assess risk. 

At Zellis, we see it as a safeguard, not a weapon. Our social media checker is designed to be transparent and fair, helping you protect your team and create a workplace where people feel safe and respected.

What are the risks of social media background screening?

Done carelessly, social media checks can raise serious concerns – including unconscious bias, privacy breaches, and even legal action. For example, rejecting a candidate solely based on their political views or protected characteristics can lead to discrimination claims. 

There’s also the danger of misinterpreting content or taking posts out of context. That’s why it’s important to combine tech-assisted screening with human oversight.

What’s the right way to do a social media background check?

Social media screening doesn’t need to be risky or invasive. With the right approach, it can be both effective and respectful. Here’s what good practice looks like:

Before screening

• Establish clear, consistent screening criteria to reduce bias and ensure fairness.
• Get candidate consent before screening begins.
• Partner with a specialist provider who combines technology and human analysis.

During screening

• Focus only on publicly available content – never ask for passwords or access private accounts.
• Flag only relevant risks, not lifestyle choices or protected beliefs.
• Document your process to demonstrate compliance with UK GDPR, equality, and employment law.

At Zellis, our partnership with Neotas delivers social media checks that are ethical by design. We help our customers manage reputational risk without compromising on ethics or privacy. It’s about protecting what matters, the right way.
