Author and journalist Grace Dent got her own back on a Twitter troll on Sunday - by pointing out he worked at a PR firm she used and asking just how much he enjoyed his job.
Mufadal Jiwaji, who works at Hill and Knowlton, tweeted that Dent reminded him of "a girlfriend I once had. By girlfriend I mean that time I accidentally made love to an ugly abhorrent horse" after her appearance on the BBC's Have I Got News For You?
But after the author questioned him, saying: "I'm wondering, as a public relations person for a firm I work with, what your thinking was in sending me this message?"
She added: "You'll bear the brunt of your idiocy at 10am tomorrow morning when you're unemployed. Good luck."
Jiwaji apologised, tweeting: "Unreservedly withdraw my vulgar and puerile comment regarding@gracedent, especially in light of the bbc doc on internet trolls last week."
The exchange caused their own Twitter storm, with many sticking criticising Dent for threatening his job.
Here in the Huff Post UK office, we're not sure it's deserved - personal abuse can never be justified.
His company said in a statement: "We're obviously aware of the comments and we're dealing with it. It's obviously being taken seriously and we're looking into it."
