Man jailed for online campaign against ex

A Brisbane woman will look to rebuild her life after her ex-boyfriend was jailed for an online harassment campaign that resulted in dozens of men approach her for sex.

Ryan Kotynski, 42, was sentenced in Brisbane District Court on Friday to four-and-a-half years jail after pleading guilty to stalking Robyn Night between 2011 and 2015.

The court heard how Kotynski impersonated Ms Night online and posted personal details, including her address, on adult websites and other pages as "revenge" four years after their relationship ended.

More than 50 men went to her Brisbane home expecting sex while she was pregnant, and suggestive messages were left on her phone and in her mailbox.

In a powerful victim impact statement, Ms Night recounted how the men arrived at her doorstep day and night during a "reign of terror" in which she became too scared to open her door and leave her house.

Kotynski will be eligible for parole on May 3, 2018.

Outside court, Ms Night said she was happy the ordeal was over, and hoped her ex had a "wonderful time in jail".
