Default Referrer

I noticed that when i have adguard fake the referrer it puts in the referrer something like "adguard" i noticed a few websites like microsoft pick up on this and it seems like various websites can pick up on this and then auto-block us?

Surely we should not be advertising to websites and apps in the referrer about adguard as that defeats the stealth part surely ? Or am i missing something? Surely the referrer should say just be an old version of chrome or something generic and not obvious were using something to block/fake data ?
