STATEN ISLAND, N.Y. -- Even after her suicide, Amanda Diane Cummings is being tormented by bullies.

Only these bullies aren't to be found in her New Dorp High School classrooms, or any other brick-and-mortar locale, and they don't care about the emotional damage they're doing to her family.

On Wednesday night and early yesterday morning, hundreds of profane comments and images flooded onto a Facebook tribute page dedicated to Miss Cummings, mocking her, and enraging her friends and loved ones.

HUNDREDS AT WAKE

The chilling Facebook messages continued even after hundreds of teens and adults -- including Assemblyman Michael Cusick (D-Mid-Island) and Rep. Michael Grimm (R-Staten Island/Brooklyn) -- gathered yesterday in South Beach for the 15-year-old's wake.

The posts came after a call to arms posted on the "/b/" forum of 4chan.org -- a website that's home to the Internet's most noxious hackers and cyberbullies.

Just before midnight, a 4chan user mocked Miss Cummings as "an hero" for committing suicide, then called on others to post on a Facebook tribute page to her: "So /b/, I please ask that you respect her memory, and write a thoughtful paragraph or too so that all of the teenage candy-asses can feel like heroes by writing how sad they are that the girl is bullied is dead."

Miss Cummings was carrying a suicide note, police say, when she jumped in front of a city bus at the intersection of Hylan Boulevard and Hunter Avenue in Dongan Hills on Dec. 27. She died six days later, on Monday. Family members attribute her death in part to years of bullying by her peers and classmates, compounded by a breakup with an older teen.

A river of venomous, anonymous comments followed on 4chan, including profane, digitally altered images, with one commenter bragging about setting up a fake account under Miss Cummings' name on Facebook.

"Photoshopped pics of her for me to dump would be appreciated," the commenter wrote.

Sure enough, comments and photos started showing up on the Facebook tribute page from people with fake names, sparking outraged responses.

Those 4chan posts have now been deleted, but screen captures catalog hundreds of similar comments, with some users bragging they were able to pin the attack on a rival anonymous message site 9gag.com. A search of that rival site shows two entries about Miss Cummings, but both have since been deleted.

"We set up memorials, they bash the memorials," said Keith Cummings, Amanda's uncle, as he arrived at A. Azzara Funeral Home yesterday afternoon. "It's not bullying, it's cowardly. You want to bully, you show yourself."

On her Facebook page, Miss Cummings' sister, Dawn Weber, called out three teens by name, including the older teen they believe she had a relationship with.

A law enforcement source said yesterday that detectives have so far found no proof, online or off, of bullying instances. Still, an NYPD investigation into the matter remains open, police officials confirmed yesterday.

Keith Cummings said he wants to point fingers but has been dissuaded by authorities -- "they're saying that's wrong, that there's no proof," he said. "If I'm hearing it, then it's proof enough for me."

He also said that a Facebook post written in the name of Cecile Weber, Miss Cummings' mother -- "This is to all you evil son of a bitches that picked on, talked about and threatened my baby. I HOPE YOU DIE and I HOPE YOU SUFFER" -- was actually written by someone else who had access to her Facebook account.

New Dorp High School senior Mike Leckow of Grymes Hill said that though he didn't see evidence of bullying firsthand, he could tell something troubled Miss Cummings.

"She was always happy, but you saw something was wrong," he said.

Leckow expressed anger over her death, and the Internet taunting -- "I just want to beat the [expletive] out of whoever did this to her."

And several of Miss Cummings' classmates railed against the comments spurred on by 4chan.

"They planned to make that page and bash on her death. They do it because they try to get their self-esteem up. It's from everyone all over the world. There's no control and stopping them," said Alyssa Vanderhoef, 15, of Dongan Hills. "It just made me furious, because she didn't deserve anything that happened."

Added Jerrell Freeman, 15, of Mariners Harbor, "I hope the people that wrote that stuff on Facebook, they find them and send them to jail."

Users of 4chan, many of whom identify with the hacker collective "Anonymous," are notorious in Internet circles for taunting and bullying teenagers and, often, taking revenge on critics of the site.

They typically hail from across the globe and hide behind shrouds of digital anonymity -- using proxies and other methods to mask their true identities and Web addresses.

In July 2010, the site's users posted the real name, phone number and address of an 11-year-old girl who was featured in an Internet video that went viral.

And when the Gawker blog network took 4chan to task in stories on its website, members responded by calling for a war against the blog network, leading hackers to breach Gawker's user accounts and steal more than a million usernames and passwords.

One of 4chan's most vocal critics, cyberbullying expert Parry Aftab, ended up the subject of a year-long harassment campaign that culminated in a prank call to police that sent a SWAT team to her New Jersey home.

Dr. Katie Cumiskey is an associate psychology professor at the College of Staten Island who conducts research into mobile technology and social media. In the shroud of online anonymity, people are more likely to behave in ways they wouldn't in person -- known as the online disinhibitation effect.

Dr. Cumiskey said that, coupled with American culture's glamorization of meanness and brutality over traits like empathy and kindness, can lead to situations like the vitriol posted on Miss Cummings' memorial site.

"To brutalize family and friends in the community who are already hurting from the loss of a loved one is really sick and inhumane," Dr. Cumiskey said. "It should make us think about what are our values as a society."
