1. This is an important example of the corrosive effects of misinformation. Yesterday I pointed out the Mail had platformed a fringe voice. https://twitter.com/adamhamdy/status/1322336637012107266?s=20

2. This is a man who believes the #COVID19 pandemic is a huge medical fraud. In the face of overwhelming evidence to the contrary, he still holds the view the pandemic ended in June. Hard to see how this doesn't qualify as a conspiracy theory.

3. Earlier this month, he spread misinformation about a hospital being empty. According to him, doctors were off playing golf. The misinformation spread so far & caused so much public anger, the hospital had to issue a public denial.

4. A hospital had to waste time and energy during a pandemic debunking what they described as a "conspiracy theory". The man responsible was given a platform in the Mail... https://www.southwalesargus.co.uk/news/18808008.coronavirus-conspiracy-claims-nevill-hall-untrue/

5. ...one of the UK's most widely read newspapers. His unfounded assertion about false positives is demonstrably false. In fact, @alanmcn1 points out that samples in his lab are sequenced, which acts as additional confirmation of infection.

6. Science should be challenged, but it must be challenged with evidence. The unsubstantiated theories of someone who refuses to believe the evidence should be ignored. They should certainly not be given a platform during a pandemic.

7. Clear, evidence-based public health measures are essential for saving lives during a pandemic. Nutty conspiracy theories, bogus models and flawed claims about Sweden are harmful. I hope newspaper editors and news producers will be far more careful about who they engage.

8. I also hope @TwitterSupport @TwitterSafety @Twitter will take a much stronger role in rooting out misinformation and outright crackpottery. It is divisive and it costs lives. https://twitter.com/alanmcn1/status/1322447090157584384?s=20
