Glitch

A glitch is a code or user error that causes a problem that can disrupt game-play or site navigation. One of the most common glitches is a "hatplosion" or "hat explosion" which allows players to wear up to three hats. It is now allowed and it's also a feature ROBLOX released in June 2010.

ROBLOX would reccomend you to report a glitch or a bug to the moderators so they can fix it.

Abuse of a glitch can result in a permanent ban from ROBLOX if a player causes exploits that is not a glitch or a bug, depending on the severity of the glitch, or how much a player abused it.

'''NOTE: Most glitches and bugs have been fixed by ROBLOX. Please do not list all of the glitches or bugs you have seen or that are not fixed yet.'''

Invisible Torso
When some people enter a game on ROBLOX, they find out that sometimes their body is invisible. If the player scrolled in and out of it, it would no longer show up to be invisible. Players can make their torso invisible with using a special program but it does not show up to other players. If a shirt has been deleted, you can wear it but it show up with an invisible shirt.

Fly Brick (walking and flying)
This is a bug that is used by many builders on ROBLOX. People usually put an unanchored and welded brick on their legs. They would fly while they walked. Some of the moderators have experienced this bug and cannot be fixed by them.

Spore+Roblox
When playing both ROBLOX and Spore they will combine.

No Delete Button
In June 2010, the delete button was removed. If anyone took something from an item, you could not delete it. You could get as many items you can if you wanted to but it still won't show up the button to delete it. People who have an item before this will show up the delete button. This has been fixed now and players who bought a hat during this issue will now show it's delete button.

"Hacker" Player Badge Exploit
The "Hacker" badge is a badge created by [CENSORED] which was added to his [CENSORED] game in 2009. This incident was spread out over 1,000 2006 users in 2010. Users 201 to 2,549 got this badge for free which only was given to 2,348 people who are all from 2005 and 2006.

Hat Giveouts
A user named Nikayah (who is also [CENSORED], [CENSORED], and others) created an exploit which one of the hats such as the Riddling Skull was given out to over 1,000 users. ROBLOX has banned him and was unbanned with another exploit in early 2009.

Free Lifetime Outrageous Builders Club
This glitch was discovered on YouTube. All the player has to do is order any Outrageous Builders Club membership, select the web address you are on, change the 5 in the end to a 6, then finish doing what you must to order.

Screen Glitch
In several places such as d4rk886's Base Wars, some users using 13+ Chat (Type Chat) "Blinded" their's and other users in the same server by holding the TAB button on their KeyBoard for a period of time and then pressing ENTER, which causes every user inside the game server to have their screen spammed with big, enlarged white letters which obstructs most of their view. Many people who were a victim of this glitch call this a hack but this is really a glitch. Not a hack. Also, most GUI's that use text can be found glitching with this glitch.

New Glitch: New Teleporter Glitch
This is a recent glitch which occurs in an offline place in Building Mode. When the player enters the teleporter taking him/her to an online server of a different game, the Free Model panel is still there in the online server. But the Free Model Panel must be opened in the offline place. Fortunately, so far it is not possible to ruin or cause havoc with this glitch.

Small Character Glitch
A long time ago, around early '09, when you equipped a kantana or a tuba, your character's avatar would be rendered much smaller than normal.

Big head
If you wear the "ROBLOX Visor in 2007" or the "Vampire Collar", your head will turn big, if you also wear another visor first.

No Torso Glitch
This happened on December 15, 2010. This glitch allowed the players avatar to have no torso. It didn't cause any problems with Roblox. It just looked weird. Your torso would be there if you joined a game. This was fixed and all players were updated back to normal on the 16th.
