that section of the script is just generating a random number (two actually) that it'll use to try and pull up a page.

Better read, is this a a loop of 500. In that loop there are 4 page accesses being attempted.

• a modlog page at the first random index
• a modlog page at the second random index
• then a search for the second index
• then another search for "fuck" + the second index number

so it uses your computer 500 times to access their page 4 different ways.

If anything, I undershot the estimate (their random number is sloppy, and will have collisions). But assuming they don't have any collisions, they use your computer to ping dbzero0 2000 times
