You must learn a basic,
I was aware of it and made this post as a fun, like I thought it would be fun for other members to know about it. Forum admins, moderators have their Bitcoin addresses on their profiles to get donations or salary.
I did not know that thanks for the information. 
but just to clear, I do know that they would have more than one addresses which might not be listed here, that's why I wrote the way of finding how many BTC they have on the addresses which are mentioned on their profiles only. I can imagine how the time it took you to go through each of the administrators BTC scanned addresses just to provide this information. One thing you should be aware OF is that most persons prefer being isolated and prefer hiding their asset in another wallet so no one will know the amount of their Bitcoin holding. The Bitcoin addressed you scanned might be one that can be seen by the public but there is this special wallet that hold most of their portfolio. I can't believe mprep will have 0 amount of Bitcoin holding.
Agreed, I was aware of all of it, but I just forgot to mention in my post that this post is for fun only but I did mention the way of finding the addresses which would have given this idea to those who would have read it full. But thanks for your feedback.
