Re-encounters of the third kind

When a person reports more than one UFO story, I feel it lessens the likelihood of it being even remotely true. A person reporting that he was struck by lightning is less credible when he says it happened to him a second time. The most credible UFO story is like a hit and run. They don't want to be found, so any encounter with them would be a mistake that the aliens wouldn't want to repeat. This is all to say that if you go to a website and have the same guy posting more than one "true story" about being abducted or seeing an alien, it's too ridiculous to be believed without some credible connection to the previous event.
