Top 10 Junior Buyer Mistakes: Why Accounts Get Banned Early

Common technical mistakes in media buying: IP changes, rotation, fingerprints, warm-up, and budget spikes. A quick checklist to keep accounts alive.

If you’re starting out in media buying and think “the creative is everything,” here’s the reality: many early bans happen before your ads even run. The reason is usually technical hygiene. Below are 10 junior mistakes that repeatedly burn accounts.

1) Logging in from different IPs within 24 hours

One login from a proxy, the next from another proxy (or home/VPN). Platforms read it as a risky location/device change.

  • One IP → one account → one session.
  • Avoid mixing home, VPN, and proxy logins within the same day.

2) IP rotation during login

If your IP changes while you’re authenticating or passing a security check, the account may get flagged or banned.

  • Use a sticky session for at least 20–30 minutes.
  • Keep the IP stable when adding payment details.

3) Refreshing the browser fingerprint between sessions

Restarting “to be cleaner” can backfire: the platform sees a new device/profile.

  • Keep the fingerprint consistent before launching ads.
  • Don’t change profile parameters without a clear reason.

4) Adding a card on the very first login

“Login → add card immediately” is a classic anti-fraud trigger for new accounts.

  • Add payment details after 2–3 normal logins.
  • Use a stable IP and a longer session (30+ minutes).

5) Starting with a Conversion campaign

Jumping straight to conversions can look aggressive when the account has no history.

  • Start with Engagement / Traffic / Video Views.
  • Move to conversions after at least 48 hours of normal activity.

6) Scaling budget instantly (+300%)

Big budget spikes often look abnormal and trigger reviews, pauses, or bans.

  • Scale gradually: +10–20% per day.
  • Only accelerate after stable performance.

7) A “15-minute warm-up”

A couple of clicks and you launch ads. For modern anti-fraud systems, that’s not enough.

  • Warm up for 60–72 hours.
  • Add organic actions and natural pauses.

8) Using a cheap datacenter proxy “just for testing”

Saving a few dollars can cost you the entire account.

  • For account longevity, mobile IPs (especially dedicated) are often safer.
  • Test in an environment that resembles real users.

9) Running multiple accounts on one IP at the same time

One exit point plus parallel sessions is a strong risk signal.

  • 1 IP/modem → 1 account (sticky).
  • Scale via an IP pool, not via more tabs.

10) Headless Chrome logins

Headless logins are widely detectable and commonly lead to bans.

  • Use an anti-detect browser or proper emulation.
  • Avoid “clean” headless logins into ad accounts.

Conclusion

Creatives drive ROI, but technical setup decides whether you’ll have accounts left to run them. Seniors don’t look for “a proxy”. They build an IP environment that doesn’t burn accounts.
