Frankly, you should just avoid interacting with women in a professional environment unless it's strictly about work.
That coworkers sometimes show interest in one another? Or, that HR complaints sometimes arise from coworker relationships?
Here's a nice article from WaPo if you'd like to read about a deluge of new complaints at HR departments and social media.

That article is paywalled.
Edit: Since I can't reply to your comment, I'll just say: You're asking for something impossible to provide. I can't post formal HR complaints on the internet. But HR should be taking social media complaints about coworkers or managers seriously and just as valid as any formal complaint. If you disagree with that, you should consider reflecting on just how serious this matter is to anyone that has felt harassed by "locker room talk", comments on their looks, and other crass speech in the workplace.
You've twice now given me examples of things that aren't "an HR complaint filed for someone showing interest." That's all I'm interested in. Can you back up that assertion, or not?
Interesting that you've managed to twist "a tweet" into being equivalent to an HR complaint. Perhaps that's the bigger issue.
But I also just scrolled through a few hundred or maybe a few thousand #metoo tweets. I didn't see a single example that fit the definition of "complaining that a co-worker expressed interest".
Can you give some examples of those tweets? I feel like that at least should be possible.
