Roblox

Idk if anyone knows about this app roblox but if you do

. Do you let your kids play it ?

My son is 5 and he plays it it's like a whole bunch of games for kids but I noticed he was playing some killing game on it And with characters like slender man and Freddy and horror characters . So lately ever since, he's been waking up at night with alot of nightmares when he plays during the day he doesn't get scared but at night every single night he wakes up screaming scared cause be has a nightmare as well. As YouTube it has so much killing and stuff I find so bad for kids his age but even when i put safe mode on YouTube and restriction they still come up ?,
