Someone calling themselves "yglgdur" added me, and its a scammer trying to sell shit. HOW do I block them so they cant see my journal?

TOTALLY - there is no place in my life for promiscuity. I am a one man man, and thats prolly why i am still single. Are there any single guys out there that also believe in being loyal and loving AND Faithfull all at the same time? If so, please sublit your resume to me for review. :)
