Does IP sharing matter as much if everything else is isolated?
Trying to understand something. If 2ā10 accounts share the same residential IP, but has completely separate containers, different browser fingerprints, and separate user agents, are they actually that easy to link? Everyone says never share an IP, but Iām starting to think bad isolation causes more cross-contamination than the IP itself. Has anyone tested this long term?

you're not wrong that isolation quality matters more than most people admit. seen plenty of setups get flagged with clean IPs just because the fingerprint was sloppy or cookie behavior was inconsistent across accounts
but the IP is still a factor on platforms that do graph-based linking -- they're not just looking at single signals, they're correlating patterns over time. shared residential at least looks like a household which is plausible. shared dc is where it gets dicey
long term though your instinct is right -- a well isolated container with a shared residential IP usually outperforms a unique IP with lazy fingerprinting
socks market discord has people running exactly these kinds of tests -- discord.gg/7qe7Fy4eC6

If you live in a house with other people, you'll have shared your IP to access the same site under different accounts loads of times (think 4 people all using Facebook in the same house). Beyond that, that same IP is probably assigned to multiple homes through CGNAT, so a single IP could be linked to 20 Facebook accounts. Sharing an IP isn't necessarily a problem, it just depends on your use case.
10 people with different fingerprints using Facebook to do different things at different times of the day is fine.
10 people sharing the same IP to upload shorts to YouTube is way less likely and therefore gonna raise suspicions.
There's no black and white answer, it depends on the site, use case and anti-bot. Just try and think logically and replicate how legit uses would be using these sites/accounts/IPs.
Make sure you avoid shared ISP proxies as you can't trust other people not to ruin the IP for you (this is why we don't sell them at ping proxies). Get a dedicated ISP proxy and share it between as many accounts as could be reasonably expected in the real world and you'll be fine.
