If you feel bothered by another member, you can put him or her on your ignore list.
You can find this option under each message with the link "Ignore member" and also in the box at the top left of the profile of the person concerned (see image).
Alternatively, you can search for members directly from your profile and put them on your list: you will find a field to enter the user name of the member you want to put on your ignore list here: www.kaufmich.com/ignorelist/show . This field provides automatic name recognition, which means that the first few letters are already sufficient to display a list of names from which you select the correct name. This member is immediately on your list and can no longer contact you.
Should you change your mind and want to make contact with the ignored member again, you can delete the member from your list on the same page.
