A British man and woman who sent abusive tweets have been jailed. 25-year-old John Nimmo and 23-year-old Isabella Sorley both pleaded guilty to the offence of “improper use of a public electronic communications network” earlier this month after being charged last month. Both have been sentenced to jail time this week. The pair took to Twitter to send abusive tweets following the Bank of England’s decision to put novelist Jane Austen on a £10 note. Journalist and activist Caroline Criado-Perez led a successful campaign to get more women on British currency, and faced up to 50 abusive and threatening tweets per hour as a result.
