the reality is the only times you should be browsing things on your phone or computer like this site at work or school is when A) you have free time and are relatively alone or B) when you're not supposed to be doing something else
I don't think any workplace would find a site like this bothersome at all, suggestive avatars are nothing
if you're a student you really shouldn't even be fulling around on your phone at school constantly and you must go to a particularly odd school if a site like this would actually offend or bother anyone when kids curse, throw things, skip class, etc. (i.e. its such a small thing who cares)
strange thread considering how tame this site is compared to many other discussion boards are on the internet today
