Opt-in history only exists where a platform runs an opt-in marketplace and records it. A discovery tool that searches public profiles does not hold a creator's opt-in log, since the creator never enrolled with it. If that history matters to you, it belongs to the marketplace the creator joined, not a search index.
Whether a platform can show a creator's history of opting into brand programs or campaigns.
Opt-in history is specific to platforms that run an opt-in marketplace and log who joined which program. A discovery tool that searches public profiles does not hold that record, because the creator never enrolled with it in the first place. It is worth being clear about this rather than implying a search index knows a creator's private program history. If opt-in status matters to your model, it belongs to the marketplace the creator opted into. Flinque is a discovery and vetting tool, which means its strength is finding and screening creators from public data across four platforms with a fake-follower score on each, not tracking opt-ins.
