Have you ever been harassed on Twitter?

Twitter, as its CEO Dick Costolo has put it, sucks at dealing with harassment and trolls. It’s been trying to get better — although its changes have sometimes misfired badly in the past. Right now, though, it’s apparently apparently trying to gauge just how big of a problem Twitter abuse really is. Its mobile app is inviting some users (specifically, verified users, as far as we can tell) to take a short survey about their personal experiences and opinions on the platform. It doesn’t seem to ask the same questions of everyone, but among other things, it asks how important it is to see interactions, how much they worry about harassment on Twitter, and the overall level of abuse users receive on other services, like YouTube. This is the first time we’ve seen this survey, but Adria Richards, who was at the center of a vitriolic fight about tech and gender in 2013 and is still regularly harassed, tweeted about receiving an invitation on February 18th.
