I kinda feel like sitting in a pool of my own sweat, dreaming about skid row girl, a bottle of apple sauce, a bunch of torreodors, and a gorilla dressed like Lucy Lui. And then it starts getting kinky... I um...
To personally I'm never invisible cause if someone wants to see what I'm reading or if I'm still on (you can tell when they last did something on here... doesnt time you out for a half hour...), then I could care less.
I hate to break it to you but it logs you out after 30 or so mins. of inactivity. You really should know that though if you were planning to use this as an alibi.
You could always give someone your password and have them making posts on your name when you kill those people.
What if I was stealing a copy of the Necrinomicon written in blood based ink on a canvas of human skin?
