So, you have just been mentioned by someone (they put a hashtag in front of your name and this hashtag gets connected to your profile page). Like this #reinergaertner.
Maybe you don’t want to be associated with that LinkedIn member or the topic? How to remove it?
Remove a mention from one post: Click on the … on the upper right of the post and choose “remove mention” and then “ok”.
Want to prevent others to mention you at all: Go to “Me” top right, choose the “privacy tab” and set under “How others see your LinkedIn activity” the option “no” at “mention or tags by others”.
You will enjoy a more uncluttered notifications stream.
