It should be considered flattery.

Wow. 5% goes to webapp registration dev. UP should have 5% if only he did not disappear

UP was not a dev and wrote zero lines of code. He did however do many good things,and some bad ones too!
5% to the Kora webapp registration dev is fair. That's the equivalent stake to a full bitcoin sender from NXT IPO. First to join something new & untested takes the biggest risk, so they deserve a larger stake. The webapp dev has contributed a lot more than just code.
Well he did the whole distribution. Doesn't need to write fancy codes to do distribution well. Need to be smart and know what it is about though.
