I do completely agree with you - I very much see it as a form of acceptable touting.
However just because that is the price that has been set it doesn't mean that they are being sold. We couldn't make the Spurs game and so for the first time we thought we would give Viagogo a go and set a price in the middle of the market range, hoping two seats together would go fairly easily. In the end we knocked it down to £45 a seat, so that we didn't end up out of pocket, and even then it didn't get sold.
It would be quite interesting to see the figures of what is actually made.
