Well, what's wrong here could be right somewhere else.
Precisely, and you adjust to the rules of the forum you're in and hoping to get some bucks from.
And in general passing off content as yours is unethical and frowned upon.
Someone set the rules.
So others can follow the rules And others needs to know the rules to follow the rules.
People don't just come to a community and know the rules. Although it's ethical/logical that the first thing you should do is inquire about the rules when you find yourself in a new place/community but then again, what if the person only got access to few of the rules and not all of it. Is he still guilty of breaking a rule he never got to know about?
Indeed, in the eyes of the law, ignorance should be an excuse for defaulters but then again, what's the law if it can achieve it's true cause, that's to punish actual offenders.
And in general passing off content as yours is unethical and frowned upon.
Some who don't know this would consider it to be just a harmless way of sharing of useful information they don't really have access to while being ignorant of the implications of their actions. Cmon, that's somehow understandable.
I'm not justifying an offence though, I'm just trying to state a fact.
