Why your automation bot got banned: DOM injection vs reverse-engineered APIs
Not all automation is created equal. Understanding how tools talk to marketplaces is the difference between smooth operations and a permanently banned account.

The three ways tools touch marketplaces
Every seller tool uses one of three approaches:
1. Official API (Safest) Platforms like eBay and Allegro offer public developer APIs. Zero risk of account action.
2. DOM Injection (Moderate risk) Chrome extensions click buttons and fill fields as if a human were typing. Safe if you keep frequencies reasonable.
3. Private API Reversing (Highest risk) The tool impersonates the mobile app directly. Fast, powerful, and guaranteed to catch a ban if the platform rotates tokens.
