I just found this interesting option when I wandering the "Modify Profile"

I've just googled it and then I found this thread (
https://bitcointalk.org/index.php?topic=868974.0)
it turns out that this option is just for Hero Member and above.
This is actually a nice, but I'm just wondering why is it only intended for Hero Member and above? Why not for every rank, or at least for a Full Member?
Is it because Hero Member has spent more time in this place, or for any reason?
Maybe the fact that the forum relies on ad revenue?
I haven't finished with 2015 yet.
2014 is as follows:
Income:
Donations: $114.78
Ads: $419,671.12
Expenses:
Fees & services: $10,886.03
Forum software project: $1,151,595.23
Other contractors: $39,297.05
Mod payments: $104,575.79
Bounties: $505.30
If it were for every rank, then there would be a serious decline in ad impressions. For Hero Members, it ensures that users have spent enough time on the forum to (probably) deserve the option to turn them off. I personally wouldn't do it - every little bit counts, after all.
Theoretically, this allows the forum to get at least 480 impressions [or a donation] from the members before they're allowed to disable the ads, though it's likely that most people post more (like myself).
