If you're really 12-year old, may I suggest you block the chat ? You shouldn't be interacting with unknown people on the Internet at that age...
Firstly it was not me that played. I allowed a younger (yes 12 year old) relative to play on the game and was not aware of what went on before. I apologise for that if true and will speak to them about it..
However it's clear from the above that at some point they were not comfortable with what was being said by Stroke-informed him/her that they felt unsafe, uncomfortable and their age and yet Stroke still persisted in making sexual comments. If you think that they are therefore "both at fault" after this!?....then that worries me that this site doesn't want to protect vulnerable users and I won't allow my younger relative to play online anymore.
If there's no effective moderation team or blocking mechanism where a user can block an individual so they can't ever join their games again, and users are allowed just to change their name..then there really shouldn't be a chat function in game or it should be censored so key words can't be used.
I've played for years and although most users are great I've also received death threats, rape threats, vile racist and sexual messages and many of these players still appear online so I guess it's just acceptable behaviour in this game
