Why Do Some Affiliate Networks Only Accept "Clean Traffic"?

Hey folks,
I’ve recently been diving deeper into affiliate marketing and noticed that some networks are super strict about traffic quality. I applied to one recently and got rejected due to a "high proxy ratio" — even though the traffic was converting decently.
It made me wonder:

What kind of traffic sources do networks typically consider "clean"?

Are there networks that are a bit more transparent or supportive for smaller teams scaling up?

And how do you all deal with rejection like this?

Would love to hear your stories or any networks you’d recommend.
Cheers,

Yup, insurance and finance offers especially are picky. From my experience, networks that use tools like IPQS or Anura will always have stricter filters. Clean traffic = real users, no VPN, and low bot scores.

You need to avoid buying traffic on some pop-up advertising platforms. These platforms are all very low-quality bot traffic.

Review your traffic, optimize it, or try applying to another network. Gaining experience and working with quality traffic will open more doors for you
