Here's a copypasta of the offending code. Other than the "_loc_#" shit the decompiler replaces variable names with, it does what it looks like it does.
There's some other stuff for the right click menu and music, but this one is the spooky shit.https://pastebin.com/gYSPRRqW
I dont know why someone would do this. I like seeing my shit posted on /f/ too, but wanting to know literally every time, where it's at, and as much info about the people posting/viewing as Flash will allow seems a bit overboard. It's not like you cant gain that info honestly by actually fucking browsing /f/.
