Two people have pleaded guilty to sending "menacing" tweets to feminist campaigner Caroline Criado-Perez.
Isabella Sorley, 23, of Newcastle, and John Nimmo, 25, of South Shields, admitted at Westminster Magistrates' Court sending the messages over a public communications network.
Journalist Ms Criado-Perez, from Rutland, received abuse after her campaign for author Jane Austen to appear on the new £10 note succeeded.
Ms Criado-Perez's campaign began after the Bank of England dropped Elizabeth Fry from new £5 notes in favour of Sir Winston Churchill, leaving no female presence on bank notes.
Sorley and Nimmo pleaded guilty to sending by means of a public electronic communications network messages which were menacing in character, contrary to Section 127(1) (A) of the Communications Act 2003.
The Crown Prosecution Service said prosecution of a separate suspect who allegedly sent offensive messages to Ms Creasy was not in the public interest.
