Coding help(Javascript)

Currently trying to code a leaderboard compiler that searches through all of a single profile's stats and leaderboards, similar to the one NotVeryGood has, but I'm trying to make it run fairly instantaneously and have more types of stats. The first problem i have with this is that if I try to run a script that goes through potentially thousands of tracks in a few seconds freerider either detects me as a bot or tries to IP ban me. The second is that I'm not exactly sure how to run this correctly through Tampermonkey, as i've never actually used it before. Any help would be appreciated, and as always have a good one
