You basically only have neutral, good and excellent. For likes and newbie, noob, member and advanced member for (non moderator/administrator) member titles. Isn't that a bit too few? Here are some suggestions for ranks (feel free to suggest your own):
-member titles:
1-10 posts: newbie
10-25 posts: noob
25-100 posts: member
100-150 posts: advanced member
150-300 posts: posting veteran
300-500 posts: spammer
500-999 posts: no life
1000+ posts: kkfenix the multiposter
-likes. the current ones don't fit so i had to rename them:
0-10 likes: unknown user
10-25 likes: somewhat liked
25-75 likes: starting to be admired
75-150 likes: popular in the positive way
150-300 likes: everyones friend
300-500 likes: loved
500-750 likes: favorited
750+ likes: worshipped
-Another good idea would be to add dislikes because this isn't facebook and everyone has a right to speak their opinion (exept extreme ones).
IF they get added, here are the names:
0-10 dislikes: unknown user
10-25 dislikes: somewhat disliked
25-75 dislikes: starting to be despised
75-150 dislikes: popular in the negative way
150-300 dislikes: everyones enemy
300-500 dislikes: hated
500-750 dislikes: despised
750+ dislikes: wished death to
While this MAY support spamming, it adds MUCH more depth. if you cannot add the one thing, if you can, add the other please.
