This reads like a manual for how to let yourself slide into confirmation bias to me.
Steps to becoming one of Slenderman's proxies (for those who are curious)
If you are a proxy and he wants you to do something, you will do that something. There is no use fighting it. Fighting it is only going to get your self in big trouble and you'll be forced to do that something anyways.

I tried levitating when I was younger, I used ouija boards, I tried telekinesis, telepathy, tried to contact the other side, scared myself stupid that I was going to become possessed thought I had paranormal experiences .. I mean it's normal teenager stuff, but you get yourself to the point where you experience some serious confirmation bias and believe you have had these experiences and therefore they are real. God, we even went on a trip to Tasmania with an EVP recorder and EMF reader .. we saw things, I mean we were in a dilapidated Georgian mansion we'd broken into in the dead of night, so it could have been rats .. but you work yourselves up to the point where you all think you saw the same things at the same time and it becomes real because others saw it too.
This thread is disturbing to read too (it's likely just a joke, or not), I'm very much wondering if these kids met the wrong people online who may have encouraged them into going forward with their plan to becoming proxies, after confirming all their beliefs of course:
