Exploiters
ROBLOX has had many famous exploiters throughout its history. One of the most famous exploiters was Dignity - an original ROBLOX player in 2008 who started performing major exploits months after his joining. One of his most famous exploits was creating large pillars at Sword Fight on the Heights IV and constantly instakilling other players. He had several aliases, one of which was "1x1x1x1". As 1x1x1x1, Dignity created free models which contained "viruses" that would create an infinite amount of messages in a place after a random amount of time. The place would eventually not be able to handle the messages and crash. The viruses proved destructive to most players' computers.
