Rob Waugh is a self-identified expert in women not having sex with men, calling femcels, "the new online terror to haunt your dreams". He is an opinion writer for Metro.co.uk. He wrote an article talking about the subreddits r/femcels and r/trufemcels. He mentioned that femcels hate stacys and quoted a very small, and not well known anti-incel Twitter handle, further suggesting that modern reporters get all their opinions from their Twitter feed instead of interviews and investigative journalism.
With regards to femcels Rob Waugh may be trying to take the approach of "taking things seriously in order to make them real", but more likely, "taking things seriously for clickbait".
