I checked powerpoetry. Someone by the name of Bhumika Fulwani has posted some poems from Hello Poetry. I don't mind my poems being plagiarized.

At least they are unintentionally proving that I am a good poet and my poems are a class apart.

I don't think that Bhumika would herself do that. It's some imposter for sure. Someone meaning to defame her.

There's nothing to be insecure about. Just take pride that your best poems are being plagiarized. And please don't come to conclusions about Bhumika. Because it must be some imposter.
