Comments



Comments, formerly known as Commentary, is a section on items in the Avatar Shop and library. Comments can be disabled by the creator of the item.

Restrictions

 * The user has to be verified.
 * 200 character limit.
 * The user may have to complete a captcha.
 * 1 minute cooldown after posting 2 comments.

Implementation
Comments were added on October 30, 2007, available for hats and t-shirts, later available to places with the delay for commenting at the same place starting off at 15 seconds.

Rise of spam comments
By later years, the administrators of Roblox decided to limit players from continuously posting comments every second. This action to extend the delay was done to combat the prevailing spam comments that were continuously appearing on Roblox, which included those that claim about the ability of a user getting lifetime Builder's Club membership and/or infinite Robux by posting the spam on a certain amount of different items and those that include a potentially harmful link. From now on, the delay was extended to 3,600 seconds (or 1 hour).

Since its creation, users often posted comments about a different subject rather than the main topic of that commentary. Other players encouraged users to do what they ask, such as joining a group or sending a trade. Some players advertised to try and get attention. However, the majority of the commentary found in Roblox consisted of "spam", where players just post comments that is off-topic and has nothing to do with the subject at all.

As of May 2013, players are required to be verified in order to comment on assets.

When users commented on catalog items (including places, decals, models, etc.), a tiny yellow check mark might appear next to the time the comment was posted. This yellow check mark indicated that the user owns the item.

Removal
At one point during the Tixapalooza sale, comments began to be disabled on many gear items and some hats, potentially due to users repeatedly posting spam comments to try to get others to play their game, send trades, post links to scam websites, buy their clothes, etc. As of now, comments will be disabled for future catalog items because of this.

On May 18, 2016, comments were then disabled from all catalog items which were made by Roblox. This was due to a massive number of bots spamming links to scam websites. Similarly, comments were removed from all games on December 2 of that year, for the same reason. As of that date, comments cannot be re-enabled due to its configuration being hidden. However, shirts, T-shirts, pants, accessories, meshes, images, decals, models, plugins, and audio will still have comments enabled if the creator allows them.

Four weeks later on December 30, the tiny yellow check mark indicator was removed due to the massive UI overhaul that occurred since late 2014.

At 2018, Roblox disabled comments in badges due to a furious number of bots that spam the comments.

Semi-reimplementation
When UGC hats were being rolled out in August 2019, creators were given the choice to enable or disable comments, meaning some avatar shop items would now allow comments.

Spam
Spam is an infamous element in the comments. The most common spam comments are variations of these types: "The person below me ___", "This is a weird glitch", "/e free", anti-spam spam, and "voice changer".
