Your social media pages are huge values as masses will find you via your Facebook, Linkedin or Instagram pages. You can easily attract masses here. As masses can see you the risk of infringements is high. If your pages have the same name as your trademark, you already have a good protection on these channels already and you can even require, via the official procedures on the respective platforms, that your names are removed from other accounts.
Social media assets are very important as they represent your service, product and company and you push your marketing efforts into these channels.
So a protection is very important.
