I think it happens to me because I mention that I'm dabbling in rust in my profile, and I guess that's a keyword they scrape for.
There are certain platforms that support smart contracts written in Rust (like Solana), so yeah, there's a chance that's triggering them.
Honestly, I'd recommend taking that off your resume, or describing it in a way that avoids using keywords. Your resume doesn't have to mention every job you've ever had, especially if they aren't relevant to the work you're looking for.
