Websites still block my actions, even when I switch to a new dedicated proxy

[Muzlap]

I bought 5 dedicated proxies from buyproxies.org.

I used one to make a bunch of yahoo email accounts, and eventually, yahoo blocked me from making more, which is understandable.

So I switched to the next proxy, and deleted all cookies, but yahoo still blocked me. I tried using all the proxies but none worked.

How could yahoo still recognise me after using different proxies?

Are you using a custom bot ? maybe it leaks your real ip adress.
You should also change your user agent.

I'm mimicking a mobile browser with the user agent. I'll try changing it but i don't think that's the problem.

How can I check if my ip is being leaked?

It is a custom bot I am using, running puppeteer.js.

I would try using a VPN because it sounds like it’s tracking your IP.

Perhaps the proxy was blacklisted, how many different proxies did you try?
