Sharedrop I think can not be a criteria either for becoming a partner. Assume we would need to give a project that seems like a scam a partner sub if they sharedroped on BTS... and then that scam becomes a reality / public and media outlets write that bitshares has been a partner of it. The criteria should be credibility, reputation and actual involvement in Bitshares ecosystem which is somewhat subjective and should be discussed among forum admins and the wider community.
