Animation Source Forums

Ok here is my question:
Is it normal for topics from one forum to be carried to the next?
I seen a lot of topics making this exchange and usualy i think it isnt good because probably the person who made the original post had a idea that was his and people claiming it like this isnt normal.
But i still dont know why people dont simply add: originally made by xyz.
Not specifically on this forum but on almost all forums that i joined related to one subject, could it be stopped?

Mmm, I'm not sure about what you think...Do you mean that some people here take topics from other forums and copy/paste them here?
I do that for the french/english side but that's different.
I would say that as long as you are the original poster of the topic, or that you only took the idea (and not copy/pasted the text of another person) it's not so much a problem?

Yes as long you are the original poster but usualy its someone else doing this from what i seen.
