I have this increasingly big pain point thinking about #Nostr's future.

Since notes cannot effectively be deleted because of the way relays work &
you sign every event/kind with your private key, 
every user is actually building an unique profile or digital replica of themselves (be your own algorithm, yada, yada). 
Especially if you add on top the ability to use your identity on all of the "other stuff".

So... enter big advertisement corporations 🎯 
What is stopping them from creating an perfect advertisement profile or doing behavioural analysis, this time without a middle man/platform, just as in mainstream social media? 
If you (accidentally) doxx yourself in the process of using nostr you will also help them, free of charge, to target and manipulate you in (non-)obvious ways, at worst even in real life.

What if those "data hoarders" decide to cooperate with government agencies and law enforcement?

Therefore I #asknostr ❓ 
Is there any way to use nostr safely at the moment without burning through new nsecs every couple months or compartmentalisation via VPN / Tor to mitigate such a "permanent record" of one's activities?
Or should we users build (mental) resilience against targeting / manipulation expecting it will be inevitable?

Also from a freedom-of-speech-angle: Should I self-censor to avoid future (more or less probable) risks?
