We are seeing this db error for some users:

SELECT * FROM vb_post_thanks AS post_thanks INNER JOIN vb_user AS user USING (userid) WHERE post_thanks.postid IN () ORDER BY post_thanks.username ASC;

MySQL Error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') ORDER BY post_thanks.username ASC' at line 1

Also users in Opera seem to be having problems using this hack, while IE appears to always work...
