Porn Star Christy Mack: Creates Domestic Violence Emojis ... Black Eyes, Bruises

The former porn star who claims she was attacked by her MMA star ex-boyfriend has launched a new line of emojis using images based on the brutal photos of her injuries ... TMZ Sports has learned.

The woman behind the concept is Christy Mack -- who claims ex-UFC star War Machine beat the crap out of her in 2014 ... nearly killing her in the process.

Mack says she was recently approached to develop an emoji app and wanted to use the platform to bring attention to victims of domestic violence ... so she created MackMoji.

"The decision to include a few emojis with a black eye, bruising, and so on is a way of bringing attention through shock value," Mack says.

"I'm willing to risk some people using them in a negative way to get the point across."

"So many are afraid to speak out, often times because they’re scared their partner will see history of their cry for help. This simple emoticon could save a life. I want everyone to know they’re not alone."

MackMoji will be released Thursday with a portion of the proceeds going to the Break the Silence Against Domestic Violence foundation.
