This max cap means any link shared on dlike can not earn more than $2 so spammers may not get links shared on site and use bid bots to ripp off reward pools.

For regular users, and users having good reputation on steemit, we are working on a progression modal, where their cap will be increased according to their worth and daily usage of site in the form of link sharing and commenting. This will be in the form of whitelisted users.

For those links which you see in top having more than $2 income, are older than this new update implementation.

I hope @karenmckersie, you get the idea of this cap and its implementation reason. You are proudly a whitelisted user. So once we have users listing implemented by the end of this week, you will definitely have better caps!
