I find it fascinating that every one of my approximately 37,500 Likes From Before disappeared except for exactly One, from the year 2015. Other members got more than a random One Like migrated over, some a few dozen or so. That, of course, puts those people ahead of the Game. Just look at the differences between what is posted on the Leaderboard/under the member's name on posts and what is posted on the right hand side panel and you can see this for yourself. So, yes, it was physically possible to bring the Likes forward.
To be fair to ALL members, exactly One Like should have been brought forward or exactly NO LIKES AT ALL. Don't enforce the perception of favoritism. That is so such a turnoff. The site loses credibility when individual members feel they have grounds to feel that they are being marginalized.
