AIO: predator?

I wanted to post this on my states subreddit abt a local potential predator. But i was afraid im misreading the situation and didnt want to begin accusing criminal behavior. Not too sure how to go abt this legality wise bc no names, etc were involved so things remained semi-anon (im a frequent city/state subreddit user). Earlier a user named u/emergency_ad6438, messaged me asking to hang out despite me stating the fact im a minor. Gave them the benefit of the doubt and thought it was some female college student 🙃. Ended up being a weird convo, looked through the profile and only found nsfw.

Is this predatory behavior?
