Looks like this is a separate feature "knowledge_credit" which is like social credit - to receive KP to your AW from other players you should donate your own KP to them.
As far as I can observe - starting credit is something like 2660KP.
Once you donate to other player's AW (using KP/AWKP/runeshards_converted_to_KP), your credit increases by amount you've donated.
Once you receive KP/AWKP/runeshardes_converted_to_KP from other player to your AW or receive AWKP as a chest reward from other player's finished AW, your credit is decreased by amount you've got.
If it become 0 - you won't be able to receive any donation to your AWs until you donate KP to someone..
If I understand your logic, it means this issue can be alleviated for those who are using WS System, since there we donate far faaaar more than we get back from chests ... and it's another nail in Net0's coffin and I'm afraid also to Swap threads. Am I right?
You say if it becomes 0 I can't receive until I donate again. OK, then when I am prevented from donating?
EDIT: I checked another friend and there I can donate even though I gave her a substantial amount of KPs already. So, the red text isn't related to my donations but the amount the other player received. Is this info changing you statement?
Finally Inno came up with working anti-pushing solution. But there is a side effect - it also prevents AW hunting in a long run.
That is a terrible side effect. Again they throwed the baby out with the bathwater.
EDIT 2: Is there anywhere mentioned this equation? How players should know when
their donation to other players vs. receiving donation from others is balanced or au contraire?
