I'll gladly add my greetings too - a highly respected

Old Welsh Guy said 'What is domain authority? (OK I know all about HITS, but am not speaking particularly about authority in that respect). Because that is another phrase that could be considered the same as trust rank. Google also bought the Hilltop algo in 2003, that could be another way of indicating some form of trust. '
I have often thought that you could almost get semi blackhat on this - in theory you can copy anyones domain name and simply add
fromxyz.whatever
Given that the opening title would be the given search term it would not take a genius to obtain high rankings for a lesser site. Or am I being too devious??
