Yea I know some people who do that too. They have like 1 or maximum 2 alts afk somewhere while the main one flies a route, and they occasionally tab back to their parked alts to get stuff that spawn. That is not worse than bots, because I've competed with those people before, but people that open 10 parked alts like this is definitely worse than bots. I get like 10% of what I used to get even if there were lots of bots flying around.
