I suppose a Website like CrackBerry could declare their editorial position on discussions of topics only suitable for adults... drinking alcohol is not suitable for children. Looking at pornography is not suitable for a sexually immature person, no matter what their age.
I would say that CrackBerry.com's "tone" is a bit uneven... you can't post the word "elliot" with "ell" replaced by "id"... it will be "bleeped" out. But I have seen words that can not be spoken or shown in print on broadcast television use in comments to blog posts etc.
It doesn't necessarily make sense... for example a list of words that are forbidden, and why they are forbidden, might be very helpful. For example, the word alluded to by "elliot", above (sorry to you folks really named Elliot out there) is banned because the management of CrackBerry.com know that posters are likely to use that word against other posters... so it's banned... ineffectively because other words aren't banned, and replacing letters with numbers or symbols usually gets past the filters anyway, so I guess what's the point?
Moderating a Web discussion forum is like parenting. There are hands on types, who watch every word and make sure to stop anything that they want to stop... then there are the hands-off types, who maybe let things get a bit out of hand before they intervene.
Mods, like parents, can't follow their charges everywhere all the time to make sure they don't do or experience anything they don't approve of... but like parents, mods can use specific situations as 'teachable moments'.
I think the OP learned today that CrackBerry.com isn't necessarily as safe for all ages as he thought... only because he personally didn't come across anything offensive in that particular way until now... but the fact is, this discussion of adult content isn't NEW to CrackBerry.com... just the OP didn't KNOW that it would happen.
So, OP, as an adult, if you found that topic so offensive personally that you don't want to risk encountering anything like it again, you'd best stay away. If you can deal with it, but are worried about other more-impressionable types like your children seeing it, then I suggest you add "crackberry.com" to the website filters on their devices (i hope you ARE doing that, or you're kids are seeing porn every single day all the time even when they don't want to) and tell your children WHY they are not allowed to visit CrackBerry.com. "Teachable moment". It is an opportunity for you to have a discussion with your kids about what is acceptable an not acceptable on the 'net, and instill your values in them.
I thought if I had kids, I might not ever EVER let them have candy of any type until they were off to school (where it would be impossible to prevent them from having it). But then, when they were on the playground at 5 years old and some other kid gives my kid a Jelly Tot or whatever, and they react "OH MY GOD WHAT IS THIS THIS IS THE MOST AMAZING THING I HAVE EVER TASTED!" what the heck am I supposed to do? They may be come a candy addict on the spot, or they may not actually care for it. Porn can be like that... I imagine that children who know about sex (not PORN) from an early age will be curious, but LESS curious because they have information, rather than having it be surrounded in mystery. Careful how much you protect your kids from knowledge about sex, because they will learn about it, and they should have the CORRECT information, rather than end up on "16 & pregnant".
