The worst thing I've saw on roblox was A freaking V image on the roblox page, no worries it went away but this became A huge discussion kinda on the roblox fandom due to the p^&n game being on the roblox top page. the game was later removed by roblox within about 30 or 40 minutes later.
Man encountering this would be insanely rare since this happened within minutes till it was removed, and I'm one of them... till I left roblox forever. so what's your's.
