I got scammed by trusting a person and because of that i lost all of my tf2 stuff
I worked really hard for all of those items.
all the donations i receive are appreciated i hope you all see this.
My most prized things were my knifes only the probss big earner and the pro ks eternal reward and my beggars pro ks. If I could just retrieve one of these back i will be contempt.
I got scammed so close to my BDAY too so I'm pretty mad.
Again thank you guys if you contribute or are just saying something nice.
