Matt said that they try to evaluate a site based on what it is now rather than what it might have been in the past.
The interesting word there is 'try'.
I know (through painful experience) of domains that have never risen above a mediocre level no matter what has been done to them, probably because of spammy links that were there in the past. After checking the Open Archive I found that at some stage the previous owners had linked back to these junk sites and I suspect this was the cause. A reconsideration request brought the usual 'no manual penalty' boilerplate. A lot of time and money went down the drain there.
In general, if a domain name has value, it ain't going to be sold for small money, let alone deleted.
