It's a damn shame when members feel they have to delete every single post they made when they want no more to do with a website.
Same thing happened with classiczcars a few years back, so they modified the system so that you could only modify a post up to 5 minutes after posting it. After that its a part of history.
Forums like this are an excellent source of information. Deleting that info shouldn't really be an option. Adding a follow-up post saying something like, 'this is all out of date, so take it as it is or leave it', instead of removing it completely would have been a better option, and maybe a bit nicer to the 99% of people on this site that didn't abuse the guy.
Damn shame.
