Glitch

A glitch (also known as bug) is a fault in the program that causes it to function improperly. Glitches usually happen almost everyday on the ROBLOX website and in games too. One of the most common glitches is a "hatsplosion" which allows players to wear more than one hat. 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.

No Delete Button
In June 2010, the delete buttom 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.
