There's proper trolling - where you apply infuriating logic to a debate about something trivial for a laugh; and there's 2016 trolling, which basically is now a catch-all term for people saying incredibly horrible things to people online, anonymously.
With that, online abuse/hassle/whatever you deem it, seems to be getting out of hand, as social media gives people the tools to act as they please online.
Instagram wants to try and tackle it, and CEO and founder Kevin Systrom has posted a blog saying that they've introduced a "keyword moderation tool", which will allow you to list words you find inappropriate or offensive, so they will be automatically deleted on your feed.
If you don't find anything offensive, then you don't need to do anything. If you're being harassed, abused, or bullied, you'll be able to set the ultimate filter for your IG feed.
IG's moderation tool has two options - the first is that you can let Instagram's algorithm screen your comments and it'll filter out any that are largely deemed to be offensive.
If that's not working for you, then there's a second option where you can create your own custom list of keywords.
The blog says: "The first feature we're introducing is a keyword moderation tool that anyone can use. Now, when you tap the gear icon on your profile, you'll find a new Comments tool."
"This feature lets you list words you consider offensive or inappropriate. Comments with these words will be hidden from your posts. You can choose your own list of words or use default words we've provided. This is in addition to the tools we've already developed such as swiping to delete comments, reporting inappropriate comments and blocking accounts."
