Ranks on the forum doesn't represent the users level of quality since we still have majority of users that got airdropped, the earlier we realized this then we'll stop expecting too much from users with high ranks. The ranks are just activity related because those mostly guilty of this habbits you speak of are those that mostly got their merits airdropped.
This user are numerous on the forum and don't actually care, hardly before you see those that earned their high ranks due to their efforts and contributions to the forum engaging themselves in such practice unless in rare occasions.
Majority are here for the cash (and they feel others are in on it) so it seems nobody care but we have those that do and their efforts aren't been publicized since the reports statistics aren't made public. Best we can do for the forum is to continue in our good deal and report those misusing the forum privilege to moderators for review.
