Character assassination on arewedatingthesameguy has made the dating scene for me impossible. How do I address this?

I?m in an incredibly difficult position. I was posted on ?arewedatingthesameguy? on Facebook in my city and it was nothing short of character assassination. The worst things were said about me, lies, and it?s at the point this has destroyed my reputation and will forever follow me. Complete defamation. She made a point of texting me a screenshot of the post after I blocked her on a different phone number to let me know she was going to ruin my life claiming I used her but she invited me up to her apartment and was giving me all the signs she wanted to have sex. The group is private therefore I?m unable to contact the admin to remove this post. I told her I would contact the police but she then said it wasn?t posted but I know it?s a lie. There are over 60,000 woman in this group which reside in or around the city. Essentially, I am unable to date. There are only two major cities in this province in Canada. I was looking at purchasing a home here but after this, I?m having to rethink what I?ll do? I am forced with having to choose between several difficult choices:
Option A- stay off online dating entirely and seek a partner who gives me a fair shake (difficult but possible).
Option B- Move out of province somewhere else in the country and legally change my name for anonymity so this doesn?t follow me.
Option C- I?m a European citizen. Live abroad.
I?m not taking this lightly. It?s eroded my mental health to the point where I?m anxious, depressed and suicidal. I?ve consistently been ghosted or been in positions where first dates after I met someone in person through for example, speed dating, has endlessly led to being ghosted afterwards. Dating prior to was fairly easy, I?m a decent looking guy but now, dating has become horrible. I need some advice on what to do, men. I dated someone who called herself a ?crazy Brazilian girl? and after sleeping with her on the first date she wanted to be my girlfriend. I listened to my gut and ended it but I wish I hadn?t slept with her. All of this could have been avoided. Worst decision of my life. It wasn?t part of my value system as well so going up to her apartment was a very bad decision.
EDIT:
There was a comment I treated her wrong. Well that?s incorrect. I treated her great. But she wanted to be my girlfriend after the first date and was giving off strong creep vibes. After respectfully messaging her and ending it, she demanded I call her which I felt was a bad decision. She then called me over 25 times and consecutively sent 32 messages threatening to publicly humiliate me where I frequent and calling me names. Clearly she was emotionally unhinged. Listening to my gut was a wise decision.
