That's terribly irresponsible behavior from a moderator... I'm sorry you're being bullied on another site. I've never seen bullying on this site, so I think you'll find that you're safer here.
If you're being sexually harassed at work, you can and should report it, and I'm pretty sure they legally have to fire the person who is sexually harassing you.
"You're too sensitive" is one of the most common things bullies and abusers say to try to justify their behavior. They try to turn it around on you so it looks like you're overreacting. They're clearly the ones who are doing something wrong, not you.
I'm sorry to hear that's been happening to you at work, I've been in similar situations in the workplace but I've found that if you report it to the right person the situation can improve.
