report user for verbal threats harrassment

User dark_beast6633 in lobby yesterday around 3:30 was on mic made threats, and vulgar comments is there anything I can do to deal with this other than block user I contacted ps3 and was told to contact you. I will not repeat what was said until I get a response but user needs to contacted about this.....never had this type of threats before. Its somewhat unbelieveable what was said
