The one I encountered on Reddit (way back when) was more focused on occasions where slightly wonky translations led to funny results, rather than just making fun of bad translations, or the people who wrote them.

E.g.

• The now-famous “Do Not Want” meme
• The German translation section that included the Nazi flag instead of the current Germany one.
• The utter nonsense written on a t-shirt I bought last time I was in Japan “Nither down on some it own american films the innocent sucker dupe speak to me blow-in baited onself because this way. Chiken just pain sent I hope come together up on the naked out-colling Rizy up road a little fat-man. BEAT SOMEWHERE”

It’s like the posts showing unnecessary quotation marks on signs - it’s not about making fun of the people who wrote the sign, it’s funny because it now conveys something else.

E.g., a sign outside a farm offering Fresh brown “eggs” for sale.
