They are your ads, go back and remove the parts you don’t want known to random searches. But it still doesn’t change the FACT that one on the internet it simply NEVER goes away. A record is left on every server that it ever passed through. Whether it was searched from Thailand or your hometown, probably hit a few hundred servers.You are assuming the threat is only from Govt sources with specialized tools and not people using OSINT for their own personal or organizational agendas. Things like photos, geo data, location information. Maybe you should talk to your friends and ask them how risky it is leaving a wide open trail. I’m not saying you can totally cover yourself but you can harden your infosec, make people work to steal your info. Like physical theft, info theft is typically restricted to opportunist who see an easy target.
