Killing skitterlings when there are 50 people at the same crystal is just being a jerk. Don't use the pursuit as a griefing air bag. I completed my pursuit very quickly while griefing maybe 5 people in total. It's quite simple really. If you are attempting to complete your pursuit during a major Arkfall:

1. Drive to the Crystal that's furthest away from the closest spawn point. The crystal that the majority of players will head to last.

2. Sit there and get all the kills you want. You can usually get 100 - 150 kills before anyone else shows up.

3. When its the last crystal left and 100 people show up its time to leave. If there's only 1-2 people just continue what you're doing.

4. While the masses start destroying this Crystal (and the final boss) drive to another Arkfall

5. If there are no other Arkfalls teleport to a friend using "Go to Friend." This will teleport you to a new phase where a lot more Arkfalls await you.

6. Repeat steps 1-5. And do NOT go to a scrapper arkfall or your kills will reset.
