If that were oudated, I'm sure someAdmin would go and update the sticky.
This really gets to a case of 'what can be used' vs. ' what is better'... Becasue bleach requires more work - the total drying for instance - it is more of a pain that Star San. However Star San and Idaphor are primarily available only from brewing stores. Bleach is available more commonly.
As to the clorine issue, may very good home brewers have used bleach and probably would still recomend it. Many who have included it in their books (Like the Joy of Homebrewing by Charlee Papazani and I think How to Brew by John Palmer). I'd guess, without having tested, that by letting the bleach dry, the Clorine evaporates. I can't garrenttee this, but it is a guess.
I say if all you have is bleach, and you are wanting to get going, go for it. But longer term, get either Star San (acid) or Idaphor(iodine) no rinse contact sanatizers. They are easier to work with, and you will be happier with the results. The primary concern about Clorine is that in beer it can produce chemicals that taste like bandaids, or plasticy.
