No Ruben, I don't have a problem with your father. I don't know him. It's just you playing games with this site.
The only one playing anything is you. It just galls at you to stay on a topic and it galls at you when anyone shows any real intelligence.
I agree the auction houses do try to get people to bid high. That's part of how they make money. As long as you are aware this takes place you need to set your price before the auction. What you need to be careful of is not being sucked in. There are coins that rarely come on the market and you may only get one chance to buy it. Then go for it. However, a majority of the coins being sold have multiple coins at the same grade level so you can be picky and not fall for the hype at a big auction. What pushes the prices up is the number of people collecting them. My auction advise is, do your homework on the coin you're interested in and then figure out what you're willing to pay for it.
