Tiffany's posts are indeed from Tiffany herself. After my thread was up to 2000 views, I went to Tiffany's web site and left her a message letting her know about my thread on peachy18's BBS. She responded to my message on her BBS in which she mentioned her post on the peachy18 BBS.
I'm as sceptical as anyone, but Tiffany is Tiffany. If in doubt, just visit Tiffany's site and click "CONTACT ME" on the home page to get to her BBS. My message to her (and her response) is under "General Discussions".
