It's no wonder he retaliated. He posts up something he was excited and proud of - being the first person to approach Guinness - and all the trolls came out of the woodwork to bring him down.
Sure, it's not the biggest, and if he is oblivious of that, then let him have his moment, and rationally prove it... (you have no idea how much I hate myself for saying this) look at what Ryan from seibertron posted on his facebook page - yes, it gave him an opportunity to heavily plug his website, but he welcomed him to the larger fandom that he is obviously unaware of, in addition to showing him that there are 4 digit collections out there (or 5 digit if you count the non-toy items)... and that's why his post was left up and the trolls were deleted.

Even my comment on your fb page could have been interpreted as being a bit snobbish, even though it was just noting that there are much larger collections out there... it missed the point of his original posting.

Sure, it wouldn't have stayed a "Guinness record" for long, but he made it possible for there to be a listing for largest Transformers collection, and for that, he earns his short period as being *their* verified largest collection.
