help

alright hi my names Jen. I was referred by my brother to come here for a problem I have. I started playing a new game that came out a few weeks ago called rivalwars. I have been playing for about 2 weeks. well 3 days ago two users named TheKing and Lucky on that site started sending me harassing pms. the king is the site owner of rivalwars I don't know about lucky. but my mom let me purchase currency on the site. so I did and these two users have been sending me sexual messages and threats. I stated that I'm 15 and just want to play the game. I have the messages they sent they said if I didn't send them nude photos they would hack my mom's bank account. I stopped playing and am not sure what to do. my brother told me to come here or amother site Gordon something. I just want someone to PISS those azzholes off I'm really upset I apologize if this seems silly I don't know how things go here. thanks Jen
