You have the option of blocking other XING members, by clicking on the three dots in their business card. Once you’ve blocked someone they will no longer be able to see your profile.
It is only possible to block non-contacts, so you may need to delete the member from your contacts list beforehand.
If you feel harassed by a message or contact request from another member that is saved in your Messages you can report it as spam. Open the message or contact request. For messages, click on the three dots in the top right-hand corner of the message window; in the case of contact requests click on “more”. You’ll then need to select Report as spam. It will then be forwarded to our customer support team.
P.S. XING is not in a position to review any harassment outside of the platform.
