The hacker, who uses the name WauchulaGhost, gained access to accounts supporting jihadist ideology and Daesh several weeks ago. After the Sunday shooting massacre in an Orlando nightclub, the hacker flooded those accounts with LGBT-related texts, and images in support of the community.
Some of the profile pictures were changed to images using phrases such as, "I'm gay and proud." For cover photos the hacker posted pictures of half-naked men cuddling happily in bed.
"I did it for the lives lost in Orlando," WauchulaGhost told Newsweek, "Daesh have been spreading and praising the attack, so I thought I would defend those that were lost. The taking of innocent lives will not be tolerated."
The hacker emphasized that although links to gay porn were included in several tweets, explicit images were not used, out of respect to the victims and so as not to offend Muslims.
Early Sunday morning, 29-year-old Omar Mateen opened fire inside a popular gay nightclub in the US city of Orlando, killing 49 and injuring at least 53 others. He was killed when SWAT teams stormed the club some three hours later.
