What if I used automator to help me search, if use, would I have any warning or will just be ban permanently?

Using any kind of automator, bot, macro, or program to perform Bing searches for Microsoft Rewards is explicitly against the Microsoft Rewards rules.

The documented guidance is:

• Do not use programs, bots, or macros to help with searching.
• Repeated violations may result in further actions against the account, including suspension and invalidation of all earned points.

The documentation does not guarantee any warning period. If automated activity is detected and considered a violation, the account can be limited or suspended, and points can be invalidated. To avoid restrictions, searches must be done manually, spread out naturally over time, and not in rapid, automated patterns.
