Don't pay attention to those PM's. They're being sent by the demons from the other side. If you put some salt, make a circle and light a candle in the middle and stand naked over the candle and sing:
Now I lay me down to sleep,
The Master of Dreams my soul will keep.
In the reflection by my side,
Evil will see itself, and it shall die
they will be gone for good and you'll see those PM's miraculously dissapeared.
