I tend to ignore their questions because they're generic and uninteresting. They also often feel like they're framed to extract something while contributing no engagement themselves, which makes me somewhat distrustful of their motive.

Personally, I like engaging in discussions where someone has genuine interest and passion about about the subject. That just doesn't exist with this user. Why ask a question and have no meaningful interaction with the response? That just doesn't comport with typical human interaction in my experience; it feels more like filling out some kind of personality test (sidenote: always refuse to do those, esp of employers. You can sell your labour, but your mind and privacy are your own). If they are making some use of the feedback, it's not demonstrated here.

At the most benign, maybe this user is just doing a poor job of starting conversations.

At the most malicious / tinfoil, they could be looking for specific opinions which may have been expressed on other social media and matching responses and speech patterns to potentially known real identities.
