Well she didn't use it in a grammatically correct way in this caption so, same old HelgaAs if Helen has ever used plethora in a sentence
ETA Trying to read anything Helga has written is like deciphering hieroglyphs to me. All the words are words but they're often in the wrong order. Sentences end oddly, without punctuation. Like none of us are perfect mate but you shouldn't need to puzzle over it like a fucking crossword.
