A redirect from wiki.bitcoin.org would enable the criminals behind these to make their stuff look even more legit than they currently can ("it's at bitcoin.org, of course it's safe").
So I think I'd personally prefer more cleanup before this happens... but I don't have time to do it all myself.
If more people could volunteer to spend even a little time on it, it would help.
Edit: To be clear, I am not promising a redirect even if such cleanup occurs!
I'm thinking you must be referring to the pages on bitcoin companies and services. I'd be willing to take a look at them and try to post here about which look especially suspicious. I'll see if I can do it over the weekend and post some kind of report in this forum. Are there other sections that you're worried are linking to scams?
