As for copypasta, that is simply a squad of folk having some harmless fun on their own profiles. Folk should be free to do what they want on their own profiles as long as it is not grossly offensive.
One can say that copypasta serves no logical purpose. Perhaps that is true.
One could also say that creating an account on an online forum in order to have virtual head butting contests akin to stags during rutting season, over blobs of ink representing fictional individuals in a Japanese children’s comic also lacks any logical purpose.
So why do we do it? Why do humans do logically pointless things? The answer is simple. Entertainment i.e. fun. We all do what we do because we find entertainment in it. Humans are not machines. We are not logic driven entities. We are all free to find fun in whatever dumb shite we find funny, including copypasta.
However, for any individual that is still grouchy over the fact that other individuals find fun in ways that they cannot understand then here are two simple bits of advice.
I) If any user posts shite that one has no interest in seeing then guess what? You can ignore them.
II) If any user posts shite that one does not want on one’s own profile then guess what? One can delete it.
It sure is convenient how simple problems often have simple solutions.
