On Twitter, I follow 138 people. All but a few use their Twitter accounts in a professional manner. There are 3 main categories: Game company employees, people who use YouTube professionally, and online content authors.
However, one of the accounts I follow is an Afterdark Alt account of someone else who only posts once or twice per day in a public manner but nearly always inappropriately. Most of his posts are explicit texts referring to his recent escapades, which at a glance are similar to non-explicit tweets. However, a few weeks ago (luckily when I was already home) he retweeted very explicit pictures of something not work appropriate. There are other accounts that I follow, which occasionally share inappropriate images during the day.
So far I have been lucky that these images weren't noticed by anyone else. A moment ago, I activated the explicit content filter on Tweetdeck, which should filter these out, but the risk remains.
My boss doesn't mind me using Twitter at work as long as it does not affect my performance, but I'm not sure that flag will fly if a batch of furry porn manages to get past the content filter. But I also don't want to stop using Twitter at work because it keeps me updated about important news and developments, both internationally, locally, and related to my job.
How can I deal with inappropriate content appearing on my twitter feed at work?
