What's a good site to blacklist someone?

Yea, it’s me again. Mr. BadLuck.
This time it’s about that same girl I mentioned before. The day after my birthday, she somehow convinces me that she’s been pregnant and that’s why we broke up. She said she knew and that’s the reason why she broke up with and even drank and you know, did stuff you’re not supposed to do when you’re pregnant. She said she had no intention on telling me and planned on aborting, but I found out from another girl which actually turned out to be her in disguise that she was and so I asked her. 2 days this went on about me trying to convince her that I will support her and the child and to try and convince her not to abort.

Long story short…Today she told me she’s been lying the whole time. Making the whole thing up. I don’t know what to believe anymore and ASAP I’m going to make her pee on a test.

I have no idea what would possess someone to do such an awful thing to anyone, but she knows that this whole month has been just one thing after another.

So, I feel the need to warn others. Is there a common or just a good site where I can tell my story and warn people?
