Which signal would you check first in this situation?
Let’s say you have 10 browser profiles.
Each one has:
- separate proxy
- separate cookies
- matching timezone
- no WebRTC leak
- no obvious DNS issue
- clean fingerprint checker result
- different account info
But after a few days, 4 of them start getting limited around the same time.
The easy answer is “bad proxy,” but I’m not sure that would always be the first thing to blame.
It could also be:
- the same login pattern
- similar content
- reused images
- same action speed
- same extension setup
- bad IP history
- browser version mismatch
- accounts created too close together
- one shared recovery method
- one repeated behavior pattern
This is the part I find interesting. When something breaks, people usually audit the technical setup first because it is easier to test.
But the actual linking signal might be something boring and non-technical.
In this kind of situation, what would you check first?
Proxy reputation, browser fingerprint, account behavior, or content overlap?
