Alert: Using a web ad blocker may identify you – to advertisers

Only by resolution

I did some tests using my usual web browsing configuration: VM, never logged-in to mail or social, over vpn. Running an ad-blocker with some sites white-listed & no script.

I visited multiple times from different IP addresses. First I changed nothing but IP address (and cleared browser history in between)

attempt 1) unique

2) 2

3) 3

So each consecutive visit from different IPs reduced my uniqueness. Then I did what I normally do which is arbitrarily modify the resolution of the VM. All consequent visits I was unique, but differentiated only by resolution.

For all visits, including the 1st three I was in a non-standard resolution.

So my fonts are the default installed with Mint, I have ad-block & no-script & flash - for those I was 1 of 2-3 thousand. Only my ever changing resolution identified me, which only works if I keep it the same really?

So whilst I will never feel secure against law enforcement, shady government agencies or determined criminals, I'm probably a bit too much effort for advertisers.

As others have mentioned though. Any advert that encroaches on my consciousness without me explicitly seeking information, only serves to make me avoid that brand.

Now, where did I put my tinfoil?
