Basically, I think the main point trying to get across is to help others out who do look at this in the workplace, school or any other place that it may affect them.
You're not losing anything at all by not even putting the pictures up, bikini, huge breast in zoom or anything that may cause someone to walk by and say.. "omg look at what so and so is looking at"
You are actually helping someone out by not having them there, believe it or not, people actually do find that stuff offensive. If you would read alot of people have said and put you in there shoes, you might understand a little more..
For example the guy who works at the school and views on his break, what if he is not liked so much by the kids? I guarentee you at almost any school in america if a student complains on a teacher it is taken seriously and then it may jeapordize his job. One simple complaint from a student passing by noticing a few odd job pictures or even a teacher could cost him his job. People will fire for the most outrageous things, i've been fired for giving my boss's dogs fresh water in the summer. It's dumb, but hey I don't really have a say in what happens, I just work there.. or did work there.
School is the same thing, for the guy who said something about the whole library example I gave, well you obviously didn't go to any high school that took things seriously. Especially now, most american high schools will take immediate action for the slightest things, trust me, I just graduated, i've seen it. Someone farted my sophmore year in class and the teacher reported it to the on campus officer and they wrote him a 300.00 ticket. Not a private school, a public high school.
All across america, things are getting stricter, more serious everyday.
You don't lose the forum by not posting half exposed girls, you in fact help gain the respect of those who it may affect for there personal reasons.
whatever it may be that you post, it's not changing the forum in any shape or form.. just making those random few excited, pleased or entertained.
