I'm currently in an awkward, social media situation that I need some advice on. 

I'm suddenly getting complaints from followers about one of the Twitter accounts I help manage.

The good news: The tweets in question aren't mine.

The bad news: It's an office politics situation where my hands are tied - I really can't do anything about the spam-like tweets. 

The worries: I'm concerned this will reflect poorly on me and people will assume I don't know how to use the Internet (uhh...I totally do and I think my love of Zombo.com proves it). I'm concerned that if I say anything, they'll hand the whole thing over to the other person and the community around the account will suffer. I'm concerned that people out there don't like me and I hate that! 

How do you proceed in a situation like this? Does anyone else have any work social media war stories to share that can help me out?
