It's like an encounter with an UFO. U see something strange, gape and awe about it, get a suspicious feeling+big impression..
then you realize you forgot to turn on the "REC" button

Like that one incident where I witnessed a P-38 diving to catch our goon.. oooh.. the P-38's outnumbered, probably he gave up on his life and determined to sacrifice his life for the cause.. boooom, he comes down.. oops, the goon takes one step aside .. 'twas like one of those 'Tom 'n Jerry' cartoons I saw.. but I digress...

(personally, I don't use it much since all the recordings are of me doing reallll stupid and kissing the ground spectacularly

)
I think however low the possibility that one's telling the truth, people should try to listen and comment sincerely. Not just wave them away "Bah~ no proof. Yer lying" I think that's sort of over-defensive attitude towards the game AH and its community. I understand meetings with continuous spawn of trolls would eventually tire even a saint, but guys, the proofless post actually might be a sincere post requesting for help or advice, or comments.
Being nice may look like a pansy, but at least the conscience(and the final taste of it all) remains clear
