This has already affected the rating of many Full Tilt Poker players. I notice they did not put my recent Midnight Madness final table appearance in my stats, even though it does show at OfficialPokerRankings.
I am not entirely sure what is the difference between the two sites as to why one is allowed to extract the data, and another is not.
"Also stated by Sharkscope admin on the blog "the lower stakes coverage has been extremely poor recently. We are continuing to work on the problem and are still optimistic about restoring full coverage; but this may take some time." This would apparently be without the blessing of Full Tilt if it ever gets restored."
