Hmm...
The post was created at 14:41. The fourteenth word is "of" and the 41st word is "prior". If we take the first letter of both of these words, we get "op". The post was also conveniently posted in October, when Frank could very easily have posted it anytime throughout the month of September, which means the number 10 has some significance. The country that has the 10th highest population density is Saint Marteen, which has national languages of Dutch and English. If we translate "op" from Dutch to English, we get "on", and if we plug "on" into an anagram solver, we get....

NO

Clearly Frank is sending very mixed messages in this post.
