In all this there are so many questions. if someone was to use a bot to extensively manipulate the BGS/PP systems, why on earth would they do it in open?
It also occurs to me, that the time investment needed to track and punish would be a huge limiting factor for FDev.
As for banning based on IPs.. There are ways and means to cheat at everything, IP hiding is just the beginning..
Perhaps the less intelligent cheaters do it in open? I hardly believe most cheaters will have coded their own bots, likely they've just downloaded someone else's work.
Ditto on the IPs (and I mean just monitoring for activity btw, not blanket-banning IPs), you've got cheaters that aren't super tech-savvy that will continue to cheat from the same IP or even forget their VPN/whatever and accidentally cheat on their IP sometime.
How many cheaters are in Elite? If it's a high number, than FDev absolutely need to be affording resources in order to kerb them. If it's a low number, then it shouldn't take huge resources to monitor their IPs and generally monitor the game data for suspicious patterns. Much of this can likely be automated as well, once FDev catch someone cheating they should hopefully be able to recognise the signatures in the data going forwards.
Point being, if it's an issue, it needs fixing. Some means will have to be worked out by FDev - this thread is somewhat of a moot point at this stage since I assume they're reading it and doing whatever it is they do with the information.
