Beware of this creep

This guy leaves the lewdest comments on swinger/hookup subreddits and messages me last night asking if I’m single. He doesn’t even know what I look like or anything about me since this is Reddit? Either blocked me or deleted his account. I wish I could figure out who he is because I feel like this is borderline harassment due to the obvious implications of his question (given what he comments on other girls’ posts).
