It seems that busy.org still does not charge their users out of their author rewards.

I suspect for a long time, and read contradicting claims by people of whether busy.org charges 15% of their users' author rewards.
I asked busy by commenting in one of their threads, but was ignored as usual.

The comments below triggered me to find some things myself, and compare them with their lack on my ledger, so to me it seems that busy.org is not only free to use, but also beneficial to use due to their vote, which costs the placeholder for one tag out of five:

As far as I remember I never had a beneficiary reward on my account.
Comment benefactor rewards appear here, in another account, and the recepient is not busy.org, I only use this example for comparison:

I searched and I found.
The root of my search was a user whom I already knew that he receives these rewards regularly/often.
So I checked his ledger for the rewards, found it, linked to the thread that paid the reward, searched its author's profile, and then I found it.
Assuming that I never had any of these on my ledger as far as I remember, do we agree now that busy.org does not charge its users, or is there another way for them to do it?
