There were many rumors that 1x1x1x1 was an exploiter or a leader of an exploiting group. Although the rumors about 1x1x1x1 have long since been debunked, many users continue to hold onto the belief that, like with John and Jane Doe.

Players speculated that he became active again after Roblox released updates, which further increased fears that "1x1x1x1 is back and will hack everyone". With 1x1x1x1's popularity within the Roblox community, Roblox has made references to him in media and events.

Alleged Rumor (and debunkment)
1x1x1x1 was used to prey on fear in one of the stories created by Shedletsky, mentioning an "evil 1x1x1x1 part" and as such many people have speculated that he is a real hacker. However, former administrator verified that 1x1x1x1 is not a hacker and started as part of one of Roblox's backstories created by Shedletsky. As discussed in the forum post:

"I posted this in a thread that subsequently died. I'm posting it here so you can refer back to it later. Keep the link to this forum. Distribute it. Tell people the truth. Let's talk about where the name comes from. Long ago, Telamon posted a number of stories about Roblox's backstory to the News. One of these included mentions of 2x2, the first brick. Copied over and over, every other brick were it's descendents.

Then, in a footnote, he mentions the evil 1x1x1x1. So that's where the name comes from. Blame John.

Let's talk about why people say he's a hacker. A guy who's (sic) name is long forgotten (not Zuka) found an exploit (not CheatEngine) to insert control scripts into online places. He sent me a message, telling me he had something to demonstrate. I joined him in Crossroads, and it started raining heads saying things along the lines of "He's coming back!" and "1x1x1x1 is coming for you!" and the likes. People in the server freaked out, I found it hilarious, he gave me instructions on how it works and I reported it to the devs. End of story.

Other people, like Dignity, would find other way to insert scripts, and people would assume that they have something to do with "the hacker group" 1x1x1x1.

Truth is, it was one guy playing off of a Roblox Lore thing."
