Puchippy
From Heyuri Historical Society
'Puchippy' was a short-lived feature on Heyuri's imageboards that was removed within just a week of it being added. It involved javascript that would scan the post-form for a few words such as "based" and "cringe" (regardless if they are being used in a regular context). And then a yellow pop-up featuring a gif of Puchiko would appear under the post form with dot points warning the user on the use of the words as well as other relevant information.
It was disliked by most users, thus it was removed shortly after the 11th townhall.
