Dead dogs, all around me, all at once, and the world turned quiet. In just about any way you can imagine any kind of dog dying, you can see it happen. If you're a dog death hater, avoid at all costs.
Some games MAY have something related to that - but none of the really popular ones do. And like the other comment says: It is against the roblox rules
Various games where players can be different animals, e.g. dogs, cats, horses. Roblox has a "reset" option which kills you and lets you respawn. It is not graphic.
there is gore in some games like blood flying everywhere in spider, but some games have an option to turn it off and also it is probably pixelated/fake looking
It depends on which Roblox games you play. There are, though, plenty of games and groups where you can roleplay as a police officer. It also depends on the roleplays and premises of the games and groups.
Some are copaganda, while some are more nuanced or even anti-cop. tl;dr, it all depends on which games you play and which groups you join
Like with any game, trolls might still be able to say ableist stuff in the chat (and generally hateful stuff about any other minority groups), but generally I feel like ableism now isn't as bad/widespread as it was back in around 2017 (also when the forums were around). Though ableism still is a problem, I feel like nowadays more people are aware of neurodiversity and are more likely to call out ableism and be respectful.
I have seen ableism on roblox only about 2-3 times within the whole of 2020 while in 2017, I had seen instances of it countless times.
Trolls might be able to bypass the filter with symbols/numbers/etc or spell out the word in blocks/bricks in building games (and trolls might say other racist stuff). Racism is against the Roblox rules and most players frown upon it.
