in the days leading up to it I was doing Jungle Inferno contracts. as such, I knew Valve didn't disable sprays on their servers.

funny enough, I did pop into Idle last Friday and found that nobody put up any sprays, even after I did so
 
People say sprays are disabled on official servers. If you see one, its either your own or you had it downloaded somewhere already.

There are rumors that there is still a spray that can crash servers and I haven't really seen many complaints about sprays being disabled, so I am going to leave it off.
 
oh, so this is legit. and oh boy, did I need to clean my userspray cache.

I'm half-surprised Valve hasn't added an option to automatically clear the spray cache on game launch
 
How will I see all the porn now =(
*stares*
*holds a funeral for my screencap gallery*
 
Cool, I can now get back to spraying a giant gleaming turd wherever an engineer faces his teleporter against the wall.... "that'll teach em"
