By searching on Twitter for the entry “XRP Dev Team” there are several accounts that send the same message to the people in question. In reality, these are bots that one recognises as they have no followers, and most of these accounts were just recently opened.
Is the whole thing related to the previous transaction of 1 billion Ripple (XRP) that occurred less than two weeks ago?
It is hard to make such a hypothesis, so it might just be a coincidence.
At the moment there’s no news from the Ripple executive, while the Ripple development team confirms the falsity of the fake accounts and therefore of the complete falsity of the message these bots are spreading.
