A man repeatedly paid cash into his ex-girlfriend's online bank account to send abusive messages to her.
Jack Roach, 29, put 41 different deposits into the Monzo account of his ex, Rachael Thomas-Tear, 24, after she blocked him on social media after their three-month relationship ended.
He used the payee reference box of the transactions to call her a "tramp", a court heard.
Roach, from Little Sutton, Cheshire, pleaded guilty to stalking at Warrington Magistrates' Court and was issued with a two-year restraining order prohibiting him from contacting his ex or approaching her home.
In a statement, Thomas-Tear, a mother-of-one, said: "While I hoped we could remain friends, it was not possible due to his change of emotions.
“I received constant calls and texts. I blocked him hoping that he would not contact me anymore but instead, he sent money to my Monzo account and would leave messages."
Roach typed abusive messages in the payee reference box for Thomas-Tear to read. One said: "Scruffy little s**g", while another read: "Little tramp, no wonder you have got no one."
It is not known how much money Roach, who claimed he wanted to rekindle their relationship after she told him she was pregnant, paid into her account in total.
Thomas-Tear reported Roach to police, saying he had also left unwanted candles and flowers on her doorstep.
In her statement, she said: “He would call from numbers showing ‘No caller id’ when I had a number of calls from my doctor about hospital appointments.
“Before all this I was a happy outgoing person but this has affected me in such a way that I am no longer able to trust people. I do not go out for fear that I might bump into him.
“If I go out I am constantly looking over my shoulder. It has impacted on my son as well. I should be able to take him to the park but I can not. I do not visit my family much as they live in the same area as the defendant. It has impacted me majorly, as they are the only support I have.”
Prosecutor Laura Simpson said: "He accepts he made some calls to the victim on a withheld number, says that she was pregnant and he accepted making bank transfers in an attempt to contact her.
“He also agreed that he would use insulting and derogatory terms if she did not respond. He accepted that he attended the victim’s property on 10 February to return belongings to her son. He also took flowers and other items to her property to lift her spirits.
“He said he did so in the chance that the relationship could be renewed.”
Roach's lawyer, Mike Gray, said: “The offence is stalking without violence and it is not stalking with the fear of violence which is more serious. That is not to downplay the seriousness of this offence.”
"He accepts that the relationship is over, has ended - he has had a relationship before. He accepts that he should not have any more involvement with the complainant and his intention is to do exactly that."
Roach also pleaded guilty to unrelated offences of possessing cannabis.
As well as the £100 victim surcharge, he was fined £50 plus £495 in costs.
He was sentenced to a 12-month community order with 135 hours of unpaid work and 20 days of rehabilitation activity with the probation service.
