Free users are typically referred to by the unofficial name "NBCers", or Non-Builders' Club.
"Bacon Noobs" for users who use the standard male avatar which came with a hairpiece called "Pal Hair", which has a overall shape and texture heavily resembling bacon.
Follow the Leader: Obstacle courses ("obbies" as they're called), which are usually floating masses of land normally filled with free modelsnote Which are models normally slapped onto places to make a place with little effort, like Lava Bricks, Spinners, Obby Pieces and such. To be fair, they are released to the public, so there isn't much excuse not to use them. . It's almost impossible to browse the front page without seeing at least one "WHO KILD SPONGBAWB OBBI" or something similar.
Tycoons are another example. Most of them are just plots of land with conveyor belts, droppers to drop stuff that earn money, flat disks on the ground to walk on, and the occasional ability to kill other players. Fortunately, some, such as Theme Park Tycoon 2 and Lumberjack Tycoon 2, don't use such mold and stand out as original tycoons.
The situation seems to have gotten better, with games of higher quality sticking on the games page for longer. Obstacle courses still appear, albeit infrequently.
Examples Of 'Leaders':
Murder Mystery (Link to original impossible, because this sequel replaced it)
Camping: Since early 2019, it's common to see an adventure game decorated with a simplistic vector design and having a casual and innocent premise, until it pulls offmacabre twists and forces the players to survive.
Any and all old versions, but especially the farther you go back. A lot of old clients have circulated around the Internet, but as of this writing (March 2018) the absolute farthest back you can go is August 2007. The 2007 client, in particular, took a very long time to find, and was only miraculously discovered by a user who found the files archived in a temporary file on an old PC. 2006 and prior still have yet to surface.
Adventure Forward: Star Savior was originally temporarily shut down for maintenance, but now remains unplayable due to the banning of its creator Explode1 before the game was reopened to the public after the repairs were supposed to be completed. (See Role-Ending Misdemeanor below for what happened.)
Long-Runners: It was publicly released in 2006 and it has received new updates and features ever since.
Starting in early 2016, a massive rise to new players was seen, which ticked off older players. Some have blamed this on Lets Players. To the uninitiated, after the old developers of Roblox were superseded by new members or simply stopped caring, things took rather drastic turns, usually for the worst. New pay systems were devised (Turbo Builder's Club, Outrageous Builder's Club), with subscriptions going into the hundreds of dollars. Scripting was locked down, with many game-breaking changes implemented that angered the scripting community.
The rise of RobloxLets Players has lead to this. Older players will often blame YouTubers, such as DanTDM, for introducing Roblox to a wider audience of children.
Official Fan-Submitted Content: Roblox occasionally holds contests where players submit original ideas for future Rthro avatars. The winning designers would win $500 and have their designs be made into official Rhtro bundles.
MisterObvious, once a respected fan animator who won 2014 Bloxy, lost all his reputation and was forced to disappear from most of the Internet after his sexual predatory behavior to underage girls on Discord was revealed.
On April 18, 2018, Pokémon Brick Bronze was taken down, presumably because of a DCMA complaint from Nintendo. Justified, as the developers were making real money off copyrighted material that they did not have permission to use. The developers later rereleased it as the spiritual successor Loomian Legacy.
Less justifiably, almost all Pokemon related games were purged in its wake, with only the most obscure games to use Pokemon themes remaining open.
Thousands of copyrighted songs submitted to the site were removed starting from June 18th, 2018. To try and counteract this, Roblox signed a license agreement with APM Music, providing a massive library of license-free music for developers to use. The reactions weren't peaceful.
Unisex Series, Gendered Merchandise: Roblox itself is a unisex game platform, but the majority of official Roblox t-shirts that are sold at retail can only be found in "boy's" clothing departments at stores. Averted with virtually all of the other Roblox merchandise items (e.g. the toys, which are aimed at both boys and girls alike).
Viral Marketing: At the time Roblox initially went live, YouTube was only just getting started. However, a few noteworthy users on there who gained fame through other kinds of videos ended up making some Roblox videos in a similar manner; this raised awareness of the game's existence tenfold. One of the most famous examples is probably Fleskhjerta (known for his The Most Stupid Deaths In Super Mario 64 series), who was probably responsible for a large percentage of 2007 users joining the game; helped, no doubt, by the snowball effect he created by inspiring other YouTube users to make "blooper" videos featuring Roblox.
Why Fandom Can't Have Nice Things: The forums were reduced to be about Roblox only in July 2017 then shut down altogether in December of the same year because the moderators didn't want to put up with the G.I.F.T. that was always around and went out of control earlier that year. It has also be theorized by some that it happened partly due to QuackityHQ who, starting in May of 2017, repeatedly used his fans to raid the forums (some even going to non-affiliated spin-off sites) because he got a 3-day ban.
