Mysterious Portuguese tweet

A Twitter search on my name just turned up a tweet in Portuguese from user @lamevaperdicio (La Meva Perdició):

"#02DL “Portava a la mà una carpeta vermella amb una etiqueta en què es podia llegir TOP SECRET”. (David D. Levine)."

This tweet is a translation into Portuguese of a sentence from my Wild Cards Volume 1 rev 2.0 story "Powers," but I can't figure out what the #02DL hashtag is or why he tweeted it. Any guesses?
