Just the usual - they accepted him back after being banned for a year but he spammed the wall for 24 hours. With that some people kicked off and started having a go at him for doing so, whilst throwing a few insults in.
Based on his original post, I very much doubt that he'll get any money from the Royal Family, and I doubt that records exist back that far into the 1490s. And if by some miracle that he did, he should sell it as it'll be worth a hell of a lot of money.
