Warning: There are spoilers ahead for season six of "Game of Thrones."

Crazed "Game of Thrones" viewers just won't let 16-year-old actor Brenock O'Connor live down Jon Snow's death.

O'Connor nabbed a recurring role on the HBO series as Olly, a boy under the care of the Night's Watch and Jon's steward. In the season five finale, he tricks Jon into stepping outside the castle walls, where he is fatally stabbed by his own men. Olly delivers the last blow.

Ever since, O'Connor and his family have received death threats online.

"I'm not Olly and I did not decide to stab Jon Snow!" O'Connor told The Argus, a local newspaper in East Sussex, England, at the start of the show's sixth season.

O'Connor says the barrage of harassment has mostly been doled out on Twitter and other social media, and it has not stopped since the finale aired in June 2015.

Some of it is very disturbing (though most of it uses O'Connor's character's name and not his own).

Some people poked fun with delightful Photoshop jobs.

Even a parody Jon Snow account on Twitter got in on the action.

Here's a little backstory. Olly sought refuge at Castle Black after his parents were killed by wildlings. Their murder left him angry at the band of nomads, so when Jon defended them in season five and granted them passage past the Wall, Olly felt personally betrayed.

He helped slay Jon in a mass stabbing, but he later paid for it with his life. In the third episode of the sixth season, titled "Oathbreaker," Jon comes back to life and sentences Olly to be hanged.

The hashtag #killolly trended on Twitter in the days after.

Apparently, the punishment wasn't enough for some "Game of Thrones" fans.

O'Connor, who's in his second year of high school, tries to let the hate roll off him. He knows it's misguided.

"If you get people from Spain and Portugal and all over the world saying they are going to kill your family, you just can't take it to heart or you would not cope," O'Connor tells The Argus.

"It's laughable how people think the show is realistic enough for them to send messages like this to someone who is not the character," he adds. "I find it quite funny."

Still, being on "Game of Thrones" has paid off for the young actor. He later earned a role in the BBC series "Dickensian" and in the children's action-adventure movie "Young Hunters: The Beast of Bevendean."

"Every day I'm thankful I got the part," O'Connor says.

Now that Jon has been resurrected, the internet is thankful, too.
