I didn't make the rules... I was not trying to bend them... so the answer is that the short individuals need to persuade the Blockchain that their amounts are correct. If the "1000" Steem threshold for Phase 1 has not been met (more than hypothetically), then they can input more Steem and still meet the minimum.
If I were them I would try. Worst case is that their Steem is returned. Best case is that they could still invest a few tens of Steem, get in, and force out some of @riosparada's claims, or at least meet his.
I think at some point, the extra input by @riosparada might need a compromise. He maybe can donate the @steemstock account, and others can claim a share. It would dilute the shares of people who followed the rules, however, if there ends up being ~1070 shares instead of exactly 1000.
