Find creators already sponsored by competitor brands

Search Instagram and TikTok for creators who have posted sponsored content for [competitor brands]. Look for #ad, #sponsored, and paid-partnership labels in recent posts, plus brand mentions in captions. For each creator capture: handle, platform, follower count, the sponsored post link, which brand sponsored them, and approximate post date. Aim for [25] creators. Skip accounts under [10k] followers and anyone whose sponsorship is older than a year. Dedupe creators who appear on both platforms into one row. Write everything to a new Google Sheet, one row per creator, and give me the sheet link plus a quick note on which 5 look strongest for [my brand].
