Orlando shooter Omar Mateen pledged allegiance to ISIS in a phone call to police negotiators during his rampage through LGBTI venue Pulse. Now, in the wake of the Orlando killings at Pulse nightclub at the weekend, an Anonymous member has started flooding ISIS sympathizer accounts with images of men in bed together, rainbow flags and pro-gay statements. Last week it was reported that members of hacker group Anonymous were hacking into Twitter accounts of ISIS supporters and flooding them with images of scantily-clad women in suggestive poses.
