When copying, as you say, "useful information" you must have the author of this information and the presence of a link from where you copied. And everything that you decided to “teach”, you once again pass off as your own “work”.
Is it possible that all the "valuable" information that you have hard-won belongs to you? Or are users so stupid that they can't read and find them on their own?
Why is the entire forum obliged to live by the rules, and you decided to adjust them as it is convenient for you?
