Ok, well I'll throw in my two cents on this whole deal
Item #1 - Personally I would be thrilled if there were no bikini clad chicks on people's sigs, HOWEVER that is just my personal preference, I respect that 1 - they aren't nude and 2 - it is up to the person the composition of his/her signature . As for preventing your kids from seeing that stuff I have found half a dozen free parental controls for the internet - the free ones aren't the best, but they are free and they work. The problem is sometimes they work too well. I would suggest using one of those Junior if it is a concern for you - K9 Blue Coat Protection (I think that is what it is called) is free for personal use. It is one of the better ones IMO.
Item #2 - It would be cool to have this filter as an option. I personally try not to swear so if you ever find a post of mine with a swear word (other than crap - which is not a swear word to me
) I am usually pretty mad. If its about the kids, see #1 - they check pages for certain words and won't display the page if they find it.
Item #3 - Good idea IMO.
In Junior's defense I understand where he is coming from, I personally don't like seeing the bikini clad women, but I don't expect everyone else to be on the same page as me (and I'm not gay
). I can't speak for Jackson, but he is usually a big proponent of free speech, and I can't imagine him blocking bikinis out of sigs.
