i have just added 3 new internal flags that can be set on user accounts:
hidefromhighscores
when this flag is set the user won't appear on the highscore board anymore. however, he can still get points as usual and his games and scores can still be seen on his profile.
it can be reverted at any time, removing this flag will make his scores appear on the highscore boards immediately again.
hidefromachievements
when this flag is set the user won't appear on the achievements top 10 anymore. however, he can still get achievements as usual and his achievements can still be seen on his profile too.
this flag is currently set on the 4 people (which includes me) that know the internal list of achievements - the list shows what you need to do to get the achievements so it would be unfair if people who know the list could participate in the competition for them.
it can be reverted at any time, removing this flag will make his achievements appear on the highscore boards immediately again.
disablescoring
when this flag is set the player will see the scores he would get in-game as usual, however, on the website all his games will appear with 0 points and also not count for the highscores.
scores they have already made in the past won't be affected and will stay, although they will slowly disappear from highscores as they expire after 60 days. the flag can be removed again at any time and the player can get scores again - however, scores from games already recorded with 0 points cannot be restored later.
the idea was brought up by our admin alex879ro because he no longer wanted to get scores, he also got the "disablescoring" flag set now.
the flags can only be set by n-ice admins, if you as a player want it for some reason simply ask us about it (on the forum or on IRC).
