I used to have a script to loop through IDs 1 through 10000 and and them all (except me). I think I only used it once, it got to the 4ks before the server host finally closed the server due to lag. A drama topic spawned where somebody asked why they were banned from a server they never visited for the reason "OMFG U R A NUUB PLS GTFO NOW LOLOLOLOLOL" or something to that effect.
It probably won't work now, and I have no plans of fixing it. It was funny, though. I may still have a picture of it...
