The bonus was implemented since the start of the project, 3 months ago, just like any promotional offer it has an expiry time so the earlier you join the more you benefit from it.

You could also have edited your older posts and add the banners to them as still get the bonus on those. You still can do so for you current unvoted posts.

There is actually a plan to extend the end of the bonus period until Dec 31st.

We have also upvoted your current comment with 10% which should be more than the 5 missed bonus.
