Pirates
Pirates will be given belli depending on their achievements in the thread. Marines will get a simpler bonus, since the whole objective of a marine is to get paid next to nothing until later levels, however they still get less rewards (or bonuses) for a job well done in a thread. Pirates, in the other hand, can loot even in beginner levels. However, in the future they will have to loot a lot to keep up with a strong marines paycheck. To make things easier here is a list to explain the maximum a pirate can earn in a thread, and it depends on how hard they worked for it among other variables I can't explain here without boring everyone reading this. Anywho, here's the list:
Pirates bellow level 10: Maximum of 10 million a thread
Pirates 10-20: Maximum of 20 million belli a thread.
Pirates 20-30: Maximum of 30 million belli a thread.
Pirates 30-40: Maximum of 40 million belli a thread.
It continues like that, forever. It should also be noted that these are maximums. Any moderator, at any given time, can look at your application, read your thread, and go 'nope' and give the user a different price. If the new pricing isn't fair to the user of the character in that thread, then he can complain to a moderator or admin of the advanced section. The issue will be discussed with the one that gave the price, and the issue will be settled. Do not harass mods too many times for a re-grade when the price is justified by the moderator, or it will come back to bite you.
Shichibukai get a flat 8 million belli a thread on top of doing pirate-y stuff to get money.
Yonku get money for doing pirate-y stuff, and a flat 1 million belli per island they own. So owning 30 islands gives the yonku a 30 million belli increase per thread on top of the treasure/money they plunder.
