I was wondering if it'd be effective to enhance everyone's privacy by making the chain analysis companies' job harder. Say, for instance, to setup a bot that randomly picks funded addresses and queries them into those SPV servers.

Example: Bob is the owner of bc1q1, bc1q2 and bc1q3. Alice is the owner of bc1q4, bc1q5, bc1q6. Charlie is the owner of bc1q7, bc1q8, bc1q9.

If they select a server, which is a spy one in this case, their addresses will be linked and they will, therefore, lose privacy. What I propose is to setup a bot that queries those addresses in a random order to make it harder for the server to recognize which address is who.

Bob's query:
Give me the balances of bc1q1, bc1q2 and bc1q3.

Bot's query:
Give me the balances of bc1q6, bc1q8, bc1q2.

etc. Can this really work in the least or there's a flaw I have not thought of?

They will still know what addresses are connected when you make and sign a transaction that is transmitted through their server.
And
If you just keep making queries and never send a TX it would be trivial to figure out that they are just bots.
And
If you ask about some of my addresses that are going out through a known server then they know at that point that you are not 100% legit. So if other addresses are known to be transacting through certain servers and you ask about them it will also be obvious that you are just looking.

I'm sure there are more issues out there too with this.
Good in theory, do not see any real way of implementing it.
