It's pathetic because posting stuff like this only fuels the rumors. If someone has heard the rumor, they may or may not believe it, but it's no surprise that someone will publicly deny being raped in a Pizza Hut, so it "proves" nothing.
If someone has not heard the rumor, they have now, and it's time for "the telephone game" to take over. Word will spread of the rumor that so-and-so was raped in a Pizza Hut, but that will eventually reduce to a story about so-and-so being raped in a Pizza Hut, not that it was only a rumor in the first place. The story has spread, and nothing has been squelched.
