Brainy

Thanks for your hints guys, the first part took me a while to figure out.
I’ve got all the crazy numbers and I am just trying to decode them using the appropriate algorithm.
I am using a method I found as the top result when searching for a particular set of characters but I am still receiving gibberish when converting to ASCII.
I have used the hint in removing particular characters, but no luck.
I just wanted to ask if anyone followed the method I hinted above?
Was there anything that had to be done to the crazy numbers before using them?
