Harry Potter star Evanna Lynch tells homophobic trolls to quit her page

Evanna, who is best known for her role as Luna Lovegood in the Harry Potter films, blasted the trolls for homophobic remarks and asked them to unfollow her Twitter, Instagram and Facebook accounts.

The Louth native (23), who previously voiced her support for marriage equality, said that she has been "worn out" from reading negative comments.

"I am making a special request to all of [my followers] today in light of an ugly Instagram thread that is really bothering me," she said.

"Simply, if you are someone who perceives homosexuality as 'disgusting' or 'f**ked up' or 'unnatural', will you do me a kindness and please unfollow me on all social media platforms."

The actress made the plea in a post on her Facebook page, which has since been shared close to 2,500 times.

"I believe in always promoting a positive message and I don't want your poison all over my carefully curated [Facebook] wall of light and positivity," she wrote.

"I cannot deal with this kind of venom, and more to the point it is wasted energy on your part to put it here."

Last year, Evanna revealed she struggled to deal with cruel comments trolls made about her on the internet.

"I learned to keep away from the public forums of the internet," she said.

"It wasn't until three years ago that I began to regard the internet as a friendly environment again."
