Hopefully not forever. When I was young and stupid and the net was a much simpler place I casually fully disclosed the problem with posting your Cisco configs with "encrypted" passwords to Usenet:

I would not do something like this today, especially not in such a full-of-myself douchey manner.
Sadly a lot of postings to the internet are basically "forever" at this point and combined with the insistence of so many companies that real names be used, we're going to have generations of younger folks who say or do something stupid (because they are young and stupid) that they can never get rid of. And that's unfortunate.
