Unfortunately, Instagram wasn't too thrilled with her move and shut down her whole account in response.
Some said Lange should have reported him, rather than "publicly shame" him, but the blogger claims she made numerous attempts to do so to no avail.
Lange has since had her account reinstated, but hopes the incident puts anyone off posting unsolicited nude photos to her inbox.
She said: "As a woman you learn to dodge unwanted advances from a young age on and even become kind of numb to it.
"Society acts as if men were animals who have no control over themselves, their actions and erections."
