I should say that I'm generally speaking a big fan of the polls functionality on LinkedIn. They provide you with some good demographics on the voters in the poll and make it easy to embed into your site and share with others via social media.
However, they also come with a pretty major flaw. We've been running a poll for the last week and it has done well in gaining plenty of votes and user interaction. We're currently at 549 votes and 89 comments, which is great.
The problem is that the poll has attracted a couple of trolls that have a clear dislike for the topic of the poll and are intent on disrupting the discussions in whatever way they can. Their latest tactic has been to swear in various foreign languages. It's all pretty childish stuff and I'd come to expect a bit more from LinkedIn users. After all, everyone there is named, and that simple premise is usually enough to dissuade people from acting too anti-socially. Sadly not in this instance though.
It wouldn't be a problem if the same moderating functionality existed on polls as they do in groups. They could either be banned by the group owner, or if enough users flag their comments they would be banned democratically. That would be absolutely lovely. Unfortunately however, on polls you can't do any of that. There is no mechanism for the poll starter to delete comments made on their poll. You can flag comments but there is no pre-defined trigger after which the user is removed. Thus far I'm aware that over 20 people haev flagged the comments made by these individuals, yet they still remain. Suffice to say that emails to LinkedIn have so far gone un-answered.
All in all it's a very frustrating experience and one that's causing us to reassess whether we use LinkedIn to create polls in future. After all it's not like there are a shortage of free apps available that do broadly similiar things. I've used PollDaddy before for instance and it's worked well, but of course they don't offer the ability for users to comment. Sticking with LinkedIn would be ideal, but when we're running polls for clients, having trolls turn up and be a nuisance is far from ideal.
