On Feb. 15, a Twitter user posted the following tweet.

Similar tweets have also surfaced, including some showing what people are describing as photos.

"Melissa I swear if u hurt Niall me and my BFF will personally come hunt u down and kill u," one user wrote. "U r holding our world and we love him so much."

Another Twitter user posted on Feb. 17, that Melissa "can f--king leave on her own or be forced out," adding, "Choose wisely bitch."

Melissa has also been bombarded with insults and threats on what is believed to be her Instagram page. A selfie she published on Tuesday has more than 24,000 comments. More than 64,000 people commented on a previous pic, which shows her with an Australian university student.

Here are several examples:

"You need to stay away from Niall, I don't want him to get hurt, I know things."

"Niall is mine."

"BITCH!"

"I F--KING HATE YOU...I KNOW @niallhoran LOVES YOU OR WHATNOT BUT I SWEAR DOWN IF ANYTHING F--KING HAPPENS TO HIM, I SWEAR TO THIS DAY, I WILL FIND YOU AND [PISTOL EMOJI] YOU."

"You look like a fish."

"UGLY."

"VERY UGLY."

"DON'T HURT NIALL JUST BREAK UP WITH HIM NOWWWWWW.' 

According to a screenshot posted by the U.K. newspaper The Daily Mail, Melissa responded to the haters, saying in an Instagram comment in one of her own posts, "For all you asking yeah Niall and I dating. Niall has not posted about because we have decided we will wait until its the right time, I haven't done anything to any of you so please stop sending me mean comments :)"

Amid all the hate, however, Melissa has also received positive comments, such as:

"SHE'S BEAUTIFUL BYEEEEE."

"She is actually pretty. Takes lot of selfies but pretty."

"You are a beautiful girl, I just [want] Niall to be happy with you or anyone."
