I don't know about the others, but this whole story smells fishy to me as according to OP, on the very same day he implemented LN, 4 persons used bitcoin in his store.
By looking at his post history as I saw he got many merit, I found he created many duplicated topics about accepting Bitcoin at his store.
More fishy to see he barely replied in his past topics. He simply created a topic to announce, update and he was out.
