“Clearly, it is not acceptable behavior,” said Diane Leiker, a spokeswoman for Littleton Public Schools. “And as soon as the administration became aware of it, they acted immediately and held the students accountable.”

Leiker said four students were suspended for three days for posting “false and defamatory” statements about teachers online.

“They posted teachers' photographs, their cellphone numbers and personal information on Zoosk, an online dating site,” said Kaitlin Davis, a Heritage High School student who saw the postings. “I think it was funny, but it was taken too far.”

Davis said the school found out about it when teachers started getting phone calls.

“Especially the ones that are married, it caused a whole bunch of drama,” said Davis. “My English teacher was talking about it this morning, and she said that now that it's on the Internet it's out there, and no matter how much we try to delete it, it's still going to be out there.”

The seniors also posted information about the prank on the senior facebook page.

Leiker said “eight or nine” students served three days of after school detention for making “inappropriate” comments on the issue.

“I think it's a great example of how social media does have unintended consequences and how we can educate parents and students on how to deal with social media,” said Leiker.

The students who were suspended had to apologize to the teachers, take down the information, and they will have to petition the District to walk in the graduation ceremony.
