if you didn't copy, how do you explain having the exact sentences, word by word and the same lower/uppercase letters
even all punctuations such as dots, commas, apostrophes and word contractions are exactly the same
the difference is only a smiley icon ~ "You do, with a smile." (credit to suchmoon)

if that's the only single instance of your copy-pasted post, you may have high chance to get a temp ban
to save you and mods time, try to remember and be honest to yourself before going to proceed with your ban appeal
though I doubt that's your only ones...
