I can understand why you put them there but as a supporter, I pay to have the pages ad-free which gives it a certain feeling and look.
1. Those aren't advertisements.
2. They're only on ONE page. It's not like the BBs stuck them in every available free spot on the site.
Just as you are not a fan of facebook (I'm not either actually), there are thousands of BB managers that are. These new buttons allow them to share the game with their friends and it might help buzzerbeater out by potentially increasing the amount of users that signup. I think your suggestion asking for the option to hide the buttons is fine, though.
I didn't mean that it's a usual ad ... but I still don't like the look of it popping up here in the BB-site. And I know that probably thousands of managers like facebook and that's just the reason why they put it there. And if we get new managers that way that's nice. But I still don't have to like those buttons. And having an option to hide them would just be nice. Let's see what the BBs have to say on this question. But for now I just did what CrazyEye suggested and now at least I don't see it on my own computer (but I don't know if I can install an ad-blocker on my iphone ...)
