Seriously plagiarism is really a great offense here, you can't just copy other people's work and post it as your own, if you see any post that you think worth posting on the forum here and it's not your post, just make sure you add source link to the post before posting and you can also quote the post to be at safer size. Nobody will ban you if you add source of where you copied the post.
I think that's one of the problem most newbies are always having, they are always too lazy to read the forum rules, why will you join a forum and you notice the forum is having rules and regulations and you won't go through it, it's not really making sense to me, the first thing I believe newbies should do immediately they join the forum is to read the rules and regulations.
