every Newbies posted the same Thread so my reply is the same also I admit that my mistake is I Only copying my Post then paste it to other post.
In theory, it's nothing wrong I guess as you didn't steal anyone else's work & claimed it as yours; that's none of the offensive IMO & should not be. But posting the same times & times doesn't look good either; instead, you can quote yourself. That would serve both purposes; avoiding posting the same every time & helping the newbie as well.
I don't think these accounts are alt of Shamm. If they were, it would be cheating but as I said, these are not probably alt & newbies often post such threads.
