JD Wetherspoon is closing down its social media accounts for all its 900 pubs and head office with immediate effect following the trolling of MPs and others.
The pub chain, which has numerous sites across Portsmouth and the surrounding areas, said the move also takes account of recent concerns over the misuse of personal data and the addictive nature of social media.
All their Twitter, Instagram and Facebook accounts will be shut down.
Tim Martin, Wetherspoon chairman, said: 'We are going against conventional wisdom that these platforms are a vital component of a successful business.
'I don't believe that closing these accounts will affect our business whatsoever, and this is the overwhelming view of our pub managers.
'It's becoming increasingly obvious that people spend too much time on Twitter, Instagram and Facebook, and struggle to control the compulsion.
'We will still be as vocal as ever through our Wetherspoon News magazine, as well as keeping the press updated at all times.
'We will also be maintaining our website and the Wetherspoon app and encourage customers to get in touch with us via our website or by speaking with the manager at their local pub.'
Wetherspoon has more than 44,000 Twitter followers and more than 100,000 followers on Facebook.
Its most popular posts have received more than 500,000 views.
